Why does a solution of a weak acid and its conjugate base act as a better buffer than does a solution of the weak acid alone? The presence of both the acid and the base provides a significant concentration of both an acid and a base, making it harder to change the pH A solution of a weak acid alone has no base present to absorb added acid. The presence of both the...

Explain why the pH does not change significantly when small amount of an acid or a base is added to a solution that contains equal amounts of the base NH3 and a salt of its conjugate acid NH4Cl.

Why is H2S a stronger acid than H2O when the conjugate base of H2O should be more stable than the conjugate base of H2S (due to O being more electronegative than S)?

Hydrogen sulfide has a pKa of 7.05. If hydrocyanic acid has a pKa of 9.21 and fluoroacetic acid has a pKa of 2.59, which one would act as a base in the presence of hydrogen sulfide instead of an acid? A. Does the acid react with the lower pKa or the base? B. Which of the two acids would act as a base in the presence of hydrogen sulfide and why? C. Of the three acids mentioned, which one would...
