Question

Soluble bases are called ________.

• A. acids
• B. both $A$ and $C$
• C. alkalis
• D. none of the above

Answer 1

The correct option is C alkalis

Bases are compounds that release hydroxyl group $\left(O{H}^{-}\right)$ in a solution medium.

Bases can be either water-soluble or they can be insoluble in water.

Water soluble bases are called alkalis.

Hence, all alkalis are bases but not all bases are alkalis.

Thus, the correct answer is an option (C).
