    Enthalpy of neutralization The purpose of this experiment is to determine the enthalpy change for the reaction between aqueous sodium hydroxide (NaOH) and aqueous hydrochloric acid (HCl). Introduction A neutralization reaction is a chemical reaction where a base and an acid react with each other. The products will always be water and a salt. The balanced reaction equation for this experiment is the reaction below (Enthalpy of neutralization, 2018). 〖NaOH〗_((aq))+〖HCl〗_((aq))→〖NaCl〗_((aq))+H_2 O_((l))

    Beginning with the principles, Brønsted-Lowry acid base theory demonstrates that an acid donates a hydrogen ions, while a base accepts hydrogen ions. Strong acids have the an easier ability to donate hydrogen ions compared to weak acids.The goal for Experiment 8 Acid-Base Equilibria: Determination of Acid Ionization Constants is to recognize how different amounts of quantitative values can alter the pH in a solution. This procedure was carried out by mixinging specific acid or base solutions together

    unknown and it is titrated with sodium hydroxide (NaOH) which serves as a titrant since its concentration is known. This is as an acid-base titration and in it the hydrogen ions from the HCl react with hydroxide ions from the NaOH to produce water. From the equation of the reaction it can be seen that HCl and NaOH react in one-to-one ratio:

    process for the production of sodium carbonate (soda ash) Generally, the ammonia will react with carbon dioxide and water to produce ammonium bicarbonate (NH4HCO3). Then, NH4HCO3 will react with salt to form sodium bicarbonate. Sodium bicarbonate will be calcined to form sodium carbonate. The Solvay process comprises of the following steps: 1. Purification of brine The first step in the Solvay process is brine purification. This step is done to produce a pure sodium chloride solution. Brine contains

    benzoic) to ions. Hydroxide ions on the other hand convert Phenols to ions. This makes them soluble in the aqueous layer as ions are soluble in water. However, addition of HCl to the aqueous ionic solutions regenerates non-ionic substances which are only soluble in the organic layer.

  • Waste Water Hardness

    1891 Words  | 8 Pages

    8. Hardness in Water and Waste Water (ethylenediaminetetraacetic acid method) Hardness is associated with the ability of water to precipitate soap and it is caused by dissolved polyvalent metallic ions. The most common polyvalent cations in fresh water are calcium (Ca2+) and magnesium (Mg2+). Chemically, hardness refers to the amount of Ca2+ and Mg2+ in water. This is due to the fact that contribution of other ions such as iron (Fe2+), strontium (Sr2+), aluminum (Al3+) and manganese (Mn2+) is usually

    experiment, citric acid was titrated with sodium hydroxide producing an endpoint between pH range of 8.3-10. (EASYCHEM, 2018) Citric acid has three acidic protons therefore it is a triprotic acid (lumen, 2018). The accurate concentration of the sodium hydroxide must be known to determine the citric acid concentration. The aim of this experiment was to determine the citric acid(weak acid) content of Lemon Juice by titrating it with standard sodium hydroxide solution(strong base). Commercially available

    titration of oxalic acid (C2H2O4) with sodium hydroxide (NaOH) is as below. C2H2O4 (aq) + 2NaOH (aq) Na2C2O4 (aq) + 2H2O (l) From the equation, it clearly showed that the 1 mole of oxalic acid (C2H2O4) will react with 2 mole of sodium hydroxide (NaOH) to produce 1 mole of oxalic acid sodium salt (Na2C2O4) and 2 moles of water (H2O). The mole ratio of oxalic acid and sodium hydroxide is 1:2 Thus, to calculate the actual concentration of sodium hydroxide (NaOH), the formula below was used
