Chapter 22, Problem 44R

To determine

To Calculate: The new pH of the solution.

Answer to Problem 44R

The new pH of the solution is $\underset{\_}{6}$ .

Explanation of Solution

Given:

The initial pH of the solution = $10$

An acid is added to the solution.

Change in pH = $4\text{ units}$

Calculation:

As per the problem,

Initially,pH of the solution = $10$

When an acid is added to the solution the pH changes by $4\text{ units}$ .

An acid lowers the pH of the solution.

Therefore, the new pH $=10-4=6$ .

Conclusion: The new pH the solution is $\underset{\_}{6}$ .
