A base
a. has a low ph in solution.
b. turns blue litmus paper to red.

Acids have low ph value. Base turns red litmus blue. Base releases hydroxyl ion(OH-) in solution. Acid releases hydrogen or hydronium ion in solution. Hence option C is correct.

Answer:

The correct option is c

Explanation:

A base is a substance that produces hydroxyl ion (OH⁻) as the only negative ion when dissolved in water. For example, NaOH (a base) dissociates in water as follows

NaOH(s)  → Na⁺(aq) + OH⁻(aq)

A base has a pH between 7-14. And a base turns red litmus paper to blue.

From the above, it can be deduced that option c is the correct answer. The remaining properties expressed in the other options are properties of an acid.
