Step 1 of 3

Given data: Ionization of weak acids bases.

Find: which species would increase the concentration of hydronium in solution the most?

Explanation:

The ionization of weak acids and bases involves the dissociation of these compounds in water.

Step 2 of 3

Let’s consider weak acids and bases separately.

Weak Acids:

A weak acid is a substance that partially dissociates into ions in water. For example, consider the generic weak acid HA:

HA(aq)↽−−⇀H+(aq)+A−(aq)

The equilibrium lies to the left, indicating that only a fraction of the weak acid molecules ionize to produce hydronium (H3​O+) ions and the conjugate base (A−)⋅

Weak Bases:

Similarly, a weak base is a substance that partially dissociates in water. Consider the generic weak base B:

B(aq)+H2​O(l)↽−−⇀BH+(aq)+OH−(aq)

Explanation:

Here, the equilibrium lies to the left, and only a fraction of the weak base molecules react with water to produce hydronium ions (H3​O+) and hydroxide ions (OH−)⋅

Step 3 of 3

Let’s analysis which Species Increases the Concentration of Hydronium (H3​O+) the Most

  1. Weak Base vs. Strong Base:
  • A strong base fully dissociates into ions in water, leading to a higher concentration of hydroxide ions (OH−) rather than hydronium ions (H3​O+). So, a strong base would not increase the concentration of hydronium ions.

 

  1. Weak Acid vs. Strong Acid:
  • A strong acid fully dissociates into ions in water, leading to a higher concentration of hydronium ions (H3​O+)⋅ So, a strong acid increases the concentration of hydronium ions more than a weak acid.

Explanation:

Hence, a strong acid would increase the concentration of hydronium ions in solution the most.

Final solution
Therefore, among the options given (weak base, strong base, weak acid, strong acid), a strong acid would increase the concentration of hydronium ions in solution the most.
