Question

You are given two solutions A and B. The pH of solution A is 6 and the pH of solution B is 8. Which solution has more ${\mathrm{H}}^{+}$ ion concentration?

Answer 1

Given data:

1. Solution A pH = 6
2. Solution B pH = 8

We know that;

1. pH is a figure expressing the acidity or basicity of a solution on a logarithmic scale on which if
2. If pH = 7, the solution is neutral.
3. If pH < 7, the solution is acidic in nature.
4. If pH > 6, the solution is basic in nature.
5. $\mathrm{pH}=-\log \left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$
6. The pH of any solution is inversely proportional to the ${\mathrm{H}}^{+}$concentration, a solution with lower pH will have a higher ${\mathrm{H}}^{+}$concentration.
7. Here, solution A has pH 6 which is lower than solution B which is 8, therefore solution A will have a higher concentration of ${\mathrm{H}}^{+}$ions.

Therefore, Solution A will have more ${\mathrm{H}}^{+}$ion concentration.
