Answer:

It ionizes completely in solution

Explanation:

The main characteristics of a strong acid is that it ionizes completely in solution. A strong acid will produce hydroxonium ions in solution.

A weak acid does not ionize completely in solution. Their ionization is very small and most times, the exists in equilibrium phase with the product formed.

A weak base also ionizes partially in solution.

A weak acid does not ionize completely in a given solution and it exists in equilibrium with the product.

The actions of strong acids are usually fast.

Answer:

$pH=4.1$

Explanation:

Hello,

In this case, for a concentration of 0.42 M of benzoic acid whose Ka is 6.3x10⁻⁵ in 0.33 M sodium benzoate, we use the Henderson-Hasselbach equation to compute the required pH:

$pH=pKa+log(\frac{[base]}{[acid]} )$
