Chemistry

1) a) Calculate the pH of a buffer that is 0.12 M in lactic acidand 0.11 M in sodium lactate. (b) Calculate the pH of a bufferformed by mixing 85 mL of 0.13 M lactic acid with 95 mL of 0.15Msodium lactate.

2) You are asked to prepare a pH=3.00 buffer solution startingfrom 1.25 L of a 1.00 M solution of hydroflouric acid (HF) and anyamount you need of sodium flouride (NaF). (a) What is the pH of thehydroflouric acid solution prior to adding sodium flouride? (b) Howmany grams of sodium benzoate should be added to prepare thebuffer? Neglect the small volume change that occurs when the sodiumbenzoate is added.

3) Calculate the solubility of Mn (OH)2 in grams per liter whenbuffered at pH (a) 7.0, (b) 9.5, (c) 11.8
