Answer:
1×10^-8 M
Explanation:
Since the solution turns blue, it means the solution is a base. Now, we shall determine the pH to know the possible hydrogen ion concentration for this solution.
1. pH = - log H+
H+ = 1×10¯² M
pH = - log 1×10¯²
pH = 2
2. pH = - log H+
H+ = 5×10¯² M
pH = - log 5×10¯²
pH = 1.3
3. pH = - log H+
H+ = 5×10¯⁴ M
pH = - log 5×10¯⁴
pH = 3.3
4. pH = - log H+
H+ = 1×10^-8 M
pH = - log 1×10^-8
pH = 8
A pH reading between 0 and 6 indicates an acid solution. A pH reading of 7 indicates a neutral solution. A pH reading between 8 and 14 indicates an alkaline/basic solution.
From the above calculations, we can see that the solution gives a pH of 8 indicating a basic solution when the hydrogen ion concentration is 1×10^-8 M
