Use the expression: pH=−log10[H+(aq)]\text{pH} = -\text{log}_{10} [\text{H}^+(\text{aq})] to calculate the theoretical pH of an aqueous solution of hydrochloric acid of concentration 1.0×10−8 mol dm−31.0 \times 10^{-8} \text{ mol dm}^{-3} at 25∘C25^\circ\text{C}. The experimental value is 6.98. Explain the differences between the two values.
