For each of the following solutions, calculate the initial pHand the final pH after adding 0.010 mol of NaOH.
1. For 240.0 mL of pure water, calculate the initial pH and thefinal pH after adding 0.010 mol of NaOH.
2. For 240.0 mL of a buffer solution that is 0.195M in HCOOH and0.280 M in HCOOK, calculate the initial pH and the final pH afteradding 0.010 mol of NaOH.
3. For 240.0 mL of a buffer solution that is 0.255 M in C2H5NH2and 0.225 M in C2H5NH3Cl, calculate the initial pH and the final pHafter adding 0.010 mol of NaOH.
