Answer 1

Answer:

Make sure you thoroughly understand the following essential concepts that have been presented above.

Explain the difference between the terms Ca and [HA] as they relate to an aqueous solution of the acid HA.

Define degree of dissociation and sketch a plot showing how the values of alpha for a conjugate pair HA and A– relate to each other and to the pKa.

Derive the relationship between acid concentration and dissociation constant to the hydrogen ion concentration in a solution of a weak acid.

Re-write the above relation in polynomial form.

Derive the approximation that is often used to estimate the pH of a solution of a weak acid in water.

Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified.

Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.
