Question 2
What effect does the concentration of ${\text{H}}^{+}$ (aq) ions have on the nature of the solution?

Answer 1

If the concentration of ${\text{H}}^{+}$ (aq) ions is increased $(>{10}^{-7})$ then the solution becomes acidic. If the concentration of ${\text{H}}^{+}$ (aq) ions is decreased $(<{10}^{-7})$ then the solution becomes basic in nature.
