Asked by JUNDY
1)A buffer solution that is 0.10 M sodium acetate and 0.20 M acetic acid is prepared. Calculate the initial pH of this solution.
The Ka for CH3COOH is 1.8 x 10-5 M. As usual, report pH to 2 decimal places.
*A buffered solution resists a change in pH.*
2)Calculate the pH when 28.8 mL of 0.035 M HCl is added to 100.0 mL of the above buffer.
3)Calculate how many mL of 0.100 M NaOH are needed to neutralize completely 55.0 mL of 0.0900 M HCl.
4)Calculate how many mL of 0.100 M NaOH are needed to neutralize completely 86.0 mL of 0.0400 M H2SO4 (forming Na2SO4 and water).
5)Calculate how many mL of 0.100 M NaOH are needed to neutralize completely 62.0 mL of 0.0600 M acetic acid.
