1. How does the Key change for a weak acid?
Tema [17]

The weak acid will have fewer ions than the strong acid of similar concentration.

The chemical reactions for a weak acid and a strong acid is given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

<h3>What are strong and weak acids?</h3>

Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.

Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.

Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.

The equation of the dissociation of strong acids and weak acids are given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.
