Citric acid, represented by H3Cit, is a triprotic acid. A student mixes together the following solutions in a styrofoam coffee cup: • 5.00 mL of 0.64 M citric acid • 45.00 mL of 0.77 M NaOH The two solutions start at a temperature of 25.5°C, and reach a final temperature of 27.8°C. The final, combined mixture has a mass of 51.6 grams and a specific heat of 4.0 J/g°C. Assume that no heat is transferred to the cup or surroundings....

1. Write balanced equations for the chemical reactions between each acid [hydrochloric (HCI), acetic acid (CH3COOH), and citric acid (H3C6H507)] and NaOH. Note that citric acid is triprotic, which will change the balance of the chemical equation. 2. Calculate how much 0.2 M NaOH wil be needed to titrate each of the acids. Each acid is 0.1 M.

Need help with below Question. Citric acid (which we can abbreviate as H3Cit) is a triprotic carboxylic acid with the following acidity constants pKa1 = 3.128, pKa2 =4.761, and pKa3 = 6.396. a) A solution is made by adding lemon juice to water until the pH is 2.20. Assuming all the acidity is from dissociation of citric acid, find the total concentration of citrate species (i.e., TOTCit) and the concentration of HCit2-. b) The solution in part (a) is diluted...
