When the number of hydroxide ions decrease then the level of hydronium ions in a solution increases.
<h3>What is pH?</h3>
pH of solution gives idea about the acidity or basicity of the solution and pH will be represented as:
pH = -log[H⁺]
If in any solution number of hydroxide ions decreases as compared to the concentration of hydronium ions, then the concentration of hydronium ions increases as a result of which acidity of the solution also increases.
