Chapter 16, Problem 5STP

Interpretation Introduction

Interpretation: The true statement for solution A having a pH of 2.00 and solution B having a pH of 4.00 needs to be determined.

Concept introduction: The pH scale measures how much the solution is acid or basic in nature.

Answer to Problem 5STP

B. Solution A is one hundred times as acidic as solution B.

Explanation of Solution

The pH scale is the logarithmic and as a result, each $\text{pH}<7$ , then the solution is acidic, and is 10 times more acidic than the next higher value.

So, solution A has pH of 2.00 is 100 times acidic than solution B of pH of 4.00.

Conclusion

The pH scale ranges from 0 to 14.
