Question

A salt derived from a strong base and a weak acid forms a basic solution (pH > 7)

a)True
b)False

Answer 1

A salt derived from a strong base and a weak acid forms a basic solution (pH > 7).

Step-by-step explanation:

A salt derived from a strong base and a weak acid forms a basic solution (pH > 7).

This statement is true. Salts that are derived from the neutralization of a weak acid by a strong base will always produce salt solutions that are basic.

For example, consider the salt sodium acetate (NaCH3COO). It is derived from the weak acid acetic acid (CH3COOH) and the strong base sodium hydroxide (NaOH). When dissolved in water, the acetate ion (CH3COO-) reacts with water to form acetic acid and hydroxide ions (OH-). The presence of hydroxide ions makes the solution basic (pH > 7).
