*Antibacterial.
* Obsolete substance.
Preparation:
Mercuric chloride can be obtained by the addition of hydrochloric acid to a hot, to concentrated solution of mercury (I) nitrate:
Mercury is one of the minority liquid elements which dissolves in oxidizing acids, producing either Hg2+ or Hg22+, depending on which reagent is in excess.
Confirmation tests for mercuric chloride:
1- After adding stannous chloride, gray precipitate will be formed:
2- Add potassium iodide, scarlet red precipitate is obtained and it's soluble in excess
Iodide:
Special reactions of HgCl2: 1- Yellow precipitate of HgO is obtained when it reacts with

1366 Words | 6 PagesCadet Eric Wiggins Date: 18 September 2014 Course Name: Chem 100 Instructor: Captain Zuniga Section: M3A Identification of a Copper Mineral Intro Minerals are elements or compounds that are created in the Earth by geological processes. The method of isolating metals in a compound mineral is normally conducted through two processes.
Chemical Equation 2 Visualizing Stoichiometry: Inquiry Lab
1286 Words | 6 PagesCassie Droelle 1510-01501 Chemical Equation 2 Visualizing Stoichiometry – Inquiry Lab Cassie Droelle 1510-01501 4-18-16 Introduction The purpose of this lab is to determine the complete balanced equation of a metathesis reaction with an unknown metal ion by first experimentally identifying the metal ion and then using stoichiometry to determine the rest of the equation. Stoichiometry is “the process by which quantities in a chemical reaction are compared” and is based on the Law of Conservation of Mass (1). The Law of Conservation of Matter “dictates that the mass of the reactants and mass of the products must be equal” (1).
Chemical Change Lab Report
432 Words | 2 PagesCaCl2 and 5 mL water, 2 tsp. CaCl2 and 2 tsp. CaCl2.The question asked at the beginning of the lab was what chemical must be present for a color change to occur. My hypothesis was that if Phenol red was present then a color change would occur. This hypothesis was true because every reaction that had phenol red experienced a dramatic color change while the other reactions did not.
Steve Zissou Life Aquatic Analysis
1400 Words | 6 PagesSteve Zissou comes from the film called The Life Aquatic with Steve Zissou. This was released in 2004. The character Steve Zissou was played by Bill Murray. Zissou is an eccentric oceanographer. Throughout the film, Steve is trying to find a mysterious creature known as a “jaguar shark”.
Sodium Chloride Lab
896 Words | 4 PagesThe purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.
Unknown Compounds
1643 Words | 7 PagesPhysically, the unknown compound was composed of white, grainy, crystal-like structures. The unknown was also odorless. From these observations, various physical and chemical testing was performed to determine properties of the unidentified compound. A series of solubility tests were performed, as shown in Table 2, and revealed that the unknown compound was soluble in water, but not in Acetone or Toluene.
Copper Cycle Synthesis
578 Words | 3 PagesIn this reaction NaOH was added to the Cu(NO3)2. The solution developed a precipitate which made the clear solution become cloudy and uniform in color (blue). The physical color change was demonstrated through the formation of the precipitate. The third step was the formation of CuO. In this reaction, the Cu(OH)2 product was heated on a hot plate and stirred continuously until the solution became colorless and a dark precipitate formed.
Compare And Contrast The Separation Of Copper Chloride And Sodium Chloride Mixture
1371 Words | 6 PagesHence in the sample only copper (II) chloride will dissolve leaving the sodium chloride behind once filtered through. The copper (II) chloride can then be obtained by evaporating the methanol; which has a boiling point of 65 degrees celsius whilst copper (II) chloride has a boiling point of 993 degrees celsius, thus allowing the methanol to be easily evaporated out of the solution eliminating concerns of the copper (II) chloride evaporating alongside the methanol. Purpose To investigate different methods of separating copper (II) chloride and sodium chloride in order to obtain the original masses of both substances.
O-Vanillin Lab Report
840 Words | 4 PagesThese color changes indicate a chemical change, which show that a reaction had occurred. In the first step when o-vanillin and p-toludine, imine was formed. The color change from green to orange suggests that imine appears as orange colored. In the second step, the addition of sodium borohydride reduced the imine into another derivative, which was yellowish lime color. The solution turned clear when acids and anhydrides was added, which indicated the precipitate were dissolved.
Synthesis Decomposition And Displacement Reaction Lab Report
1316 Words | 6 PagesFor Station 4 , the magnesium and zinc turnings blackened when introduced to Cu(NO3)2 . Copper (II) nitrate, zinc nitrate and magnesium nitrate all changed colour when sodium carbonate was added. b)Magnesium is most reactive (#1). Zinc is second most reactive (#2). Copper is the least reactive (#3).
Water Bromine Research Paper
673 Words | 3 PagesWhen you go swimming in the summertime there 's Bromine in the pool. When it’s a summer night and you go in the hot tub there Bromine in the spa to. Science keeps growing awakening the world with new science. While you think there 's only water in the pool, your wrong. There are multiple different thing in the there but bromine helps water a lot.
Empirical Formula Of Copper Chloride Lab Report
729 Words | 3 PagesThe objectives of this experiment were to use knowledge of chemical formulas and chemical nomenclature to experimentally determine the empirical formula of copper chloride. Common laboratory techniques were used to conduct a reaction between copper chloride and solid aluminum in order to get rid of the water of hydration. The amount of water of hydration in the sample of copper chloride hydrate was calculated by measuring the mass before and after heating the sample. Afterwards, an oxidation-reduction reaction was conducted, resulting in elemental copper.
Ionic And Covalent Compounds Lab Report
902 Words | 4 PagesProperties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
Water Hydration Lab Report
603 Words | 3 Pages⋅ 5H2O, which has about 36.0%, and CuCl2 ⋅5H20 (21.17%). Materials: Ring stand, ring clamp, evaporating dish, Bunsen burner, clay triangle, crucible tongs, electronic balance, sample of hydrated salt. Methods:
Hydrochloric Acid And Sodium Thiosulphate Lab Report
1539 Words | 7 PagesIntroduction The goal of the experiment is to examine how the rate of reaction between Hydrochloric acid and Sodium thiosulphate is affected by altering the concentrations. The concentration of Sodium thiosulfate will be altered by adding deionised water and decreasing the amount of Sodium thiosulphate. Once the Sodium thiosulphate has been tested several times. The effect of concentration on the rate of reaction can be examined in this experiment.
