Question

The pH of the alkaline solution is __________.

• A. True
• B. False
• C. less than 7
• D. equal to 1

Answer 1

The correct option is B False

Most bases are insoluble in water. The few which are soluble are called alkalis. When alkalis dissolve in water, they produce the hydroxide ions. The pH of the alkaline solution is more than 7.
They are usually metal oxides, metal hydroxides, metal carbonates or metal hydrogen carbonates.
Examples are $\text{NaOH}$ and $\text{KOH}$.
