Write a chemical reaction and a few words to explain why the pHof the formic acid buffer above goes up only tenths of a pH unit(from about 3.6 to about 3.7 pH units) when a few drops of 0.10 MNaOH solution are added to it, instead of going up much more toabout pH=10. {Note that if the same amount of NaOH were added to 20mL of 0.00025 M HCl (which also has pH=3.6), the pH would go up toabout pH=10. Explain qualitatively â€“ no calculation is needed.}
