Ответ:
The ratio of [A⁻] / [HA] is 100
Explanation:
The structure of the formic acid (Weak acid), is in the picture.
Using H-H equation, we can determine the ratio of [A⁻] / [HA] for a weak acid as Formic Acid:
pH = pKa + log₁₀ [A⁻] / [HA]
Where A⁻ is the conjugate base of the weak acid, HA.
Solving for formic acid at pH = 5.75:
5.75 = 3.75 + log₁₀ [A⁻] / [HA]
2 = log₁₀ [A⁻] / [HA]
10^2 = [A⁻] / [HA]
The ratio of [A⁻] / [HA] is 100Ответ:
