Question

When a weak acid and a strong base are mixed, the resulting pH will be 7 (circle the correct answer).

Answer 1

Answer: The correct answer is False.

Explanation:

There are three types of solution: acidic, basic and neutral

To determine the type of solution, we look at the pH values.

• The pH range of acidic solution is 0 to 6.9
• The pH range of basic solution is 7.1 to 14
• The pH of neutral solution is 7.

When a strong acid and a weak base reacts, it leads to the formation of acidic solution. The pH of these solutions are found to be below 7.

When a strong base and weak acid reacts, it leads to the formation of basic solution. The pH of these solutions are found to be above 7.

When a strong acid and strong base or weak acid and weak base reacts, it leads to the formation of neutral solutions. The pH of these solutions are found to be equal to 7.

Hence, the correct answer is False.
