ANS:B - > 7

The pH value of an alkaline solution is greater than 7. The pH scale measures the acidity or basicity of a solution. A pH value less than 7 indicates acidity, while a pH greater than 7 indicates alkalinity. Alkaline solutions have a pH greater than 7 because they contain higher concentrations of hydroxide ions (𝑂𝐻−OH−) compared to hydronium ions (𝐻3𝑂+H3​O+). Therefore, the correct statement is: 7
