Contact Process & Sulfuric Acid
Sulfuric Acid (H2SO4) is a colorless liquid that is used to make chemicals like hydrochloric acid, nitric acid, and sulfate salts. It is also used in the production of washing detergents, dyes, explosives, and drugs. It is also used to refine gasoline and other petroleum products. Sulfuric acid is also used in cleaning metals, like iron and steel. There are two different processes to create sulfuric acid, one is called the lead chamber process and the other is called contact process. The lead chamber process is significantly older between the two, and is used to produce most of the acid that fertilizers are made with. The lead chamber process also produces acid that is quite diluted. The contact process produces a significantly concentrated acid, and requires raw materials and the use of expensive catalysts. (Sulfuric Acid, The Columbia Encyclopedia).
Contact Process produces sulfur dioxide, it also converts the sulfur dioxide into sulfur trioxide; this is a reversible reaction that happens during the middle of the conversion, and then it also converts the sulfur trioxide into sulfuric acid. The production of sulfur dioxide on an industrial scale requires the combination of sulfur and oxygen.
S + O2 → SO2
This produces sulfur dioxide. Another way is to heat sulphide ores such as pyrite, and this should be done in an excess of air. For example,
4FeS2 +

Smelting is the other process, which uses heat and a chemical reducing agent to decompose a metal oxide into a pure metal. Through this process, which is a redox reaction, the transfer of electrons between the two chemical components takes place. The element that loses an

Also, if the chemical reaction occurred, to determine if it formed a precipitate or gas. Safety General Safety Precautions: Do not touch the chemicals Use of gloves and coats are recommended, use of goggles should be required Keep the work area clean Dispose of the chemicals properly, DO NOT dispose them in the sink Clean up your work station Wash your hand before and after the lab Make sure all chemicals are labeled correctly NEVER return chemicals to reagent bottles Use the wafting technique to smell the chemical Clean up spills immediately

How Can Alka Seltzer Act As A Buffer Against Acid Rain
1463 Words | 6 PagesBecause sulfuric acid is an example of a pollutant that contaminates rainfall naturally, adding small amounts to distilled water will model acid rain. Synthetic acid rain is used to simulate the effects of acid rain on smaller and controlled scales, such as this experiment. Synthetic acid rain is overall a good tool to use a representation. A possible solution to stop acid rain from seeping into the soil and dissolving nutrients is to add a buffer to soil to counteract the effects of acid rain. Alka-Seltzer is a buffer because in order to maintain a balanced pH level, which is 7, you must have equal amounts a base an acid.
Reaction Lab
621 Words | 3 PagesThe reaction between Hydrochloric Acid and Sodium Carbonate led to the formation of gaseous Carbon Dioxide, aqueous water, and aqueous solution of Sodium Chloride as a result of all compounds containing alkali metals solubility. Lastly, Copper Sulfate and Sodium Carbonate reaction produced an aqueous sodium sulfate solution and a solid precipitate of Copper (II) Sulfite because of all alkali metals and sulfates ability to be soluble and the rule that any compound containing CO₃ is insoluble. In the end, the hypothesis that if we react mystery chemicals with one another, we will be able to identify the reactants and products, create balanced equations, and observe properties because of our prior knowledge learned throughout the course of the unit and using the known chemical reaction was accepted by the data

Unknown White Compound Lab Report
1367 Words | 6 PagesAbstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.

The copper and hydrogen gas replace each other. Balanced Chemical Equation: CuO (s) + H2SO4 (aq) —> CuSO4 (aq) + H2O (l) Reaction 5: when zinc is added to the copper (II) sulfate solution, a single displacement reaction will occur.

Certain parts of the gas division are evacuated (depentanized) and others have their substance structure changed (isomerized). A couple dirtying impacts are cleared (desulfurized), and others have portions added to convey the last thing (reformulated fuel).
Sodium Thiosulfate And Hydrochloric Acid Lab Report
3578 Words | 15 PagesAim: To find out the relationship between the greater concentration of sodium thiosulfate when mixed with hydrochloric acid and the time it takes for the reaction (the time it takes for the solution to turn cloudy) to take place and to show the effect on the rate of reaction when the concentration of one of the reactants change. Introduction: The theory of this experiment is that sodium thiosulfate and hydrochloric acid reach together to produce sulfur as one of its products. Sulfur is a yellow precipitate so, the solution will turn to yellow color while the reaction is occurring and it will continue until it will slowly turn completely opaque. The reaction of the experiment happens with this formula: “Na2 S2 O3 + HCL =
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.
