Citric Acid has 3 pKas: 3.13, 4.76, and 6.39. How many grams of sodium citrate monobasic (HOC(COONa)(CH2COOH)2) and citric acid (HOC(COOH)(CH2COOH)2) are needed to make 300 mL of a 10 mM citrate buffer of exactly pH 2.8? The molecular weight of sodium citrate monobasic (NaH7C6O7) is 214.11 g/mol and that of citric acid (H8C6O7) is 192.12 g/mol.

f.) How many grams of Sulfuric Acid is needed to make a 0.125 normal solution in 0.750 L of water.
As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...
