Question

A solution is said to have ___ character when its pH value is greater than seven. (basic/acidic)

Answer 1

Bases change red litmus to blue. Bases produce hydroxide ions $\left({\mathrm{OH}}^{-}\right)$ when dissolved in water. The pH value for bases varies from more than 7 to 14 whereas the pH value for acids varies from more than 0 to 6.

Hence, a solution is said to have a basic character when its pH value is greater than seven.
