The pH of the hydrogen chloride, HCl solution having a concentration of 0.03 M is 1.52
What is pH ?
This is simply a measure of the acidity / alkalinity of a solution.
The pH measures the hydrogen ion concentration while the pOH measures the hydroxide ion concentration
How to determine the concentration of H⁺
Dissociation equation
HCl(aq) —> H⁺(aq) + Cl¯(aq)
From the balanced equation above,
1 mole of HCl contains 1 mole of H⁺.
Therefore,
0.03 M HCl will also contain 0.03 M H⁺
How to determine the pH
- Hydrogen ion concentration [H⁺] = 0.03 M
pH = –Log H⁺
pH = –Log 0.03
pH = 1.52
