Question- 1 liter of a buffer composed of NaHC2O4 and Na2C2O4 has a pH of 4.0 and a total molarity 1. (a) What would the effect on the pH be of adding 1 gram of sodium hydrogen oxalate to this buffer? (b) What would be the effect on the pH of adding 1 gram of sodium oxalate to the original buffer? (c) What would be the effect on the pH of adding 10 mL of 2 M sodium hydroxide to the original buffer? (d) What would be the effect on the pH of adding 100 mL of 2 M sodium hydroxide to the original buffer?
