Chapter 6: Problem 40

Which of the following \(\mathrm{pH}\) values at \(25^{\circ} \mathrm{C}\) corresponds to the strongest acid? (a) 2 (b) 4 (c) 6 (d) 8

Short Answer

Expert verified
(a) 2 (b) 4 (c) 6 (d) 8 Answer: (a) 2

Step by step solution

01

Understand the pH scale

The pH scale ranges from 0 to 14, where a pH value of 7 indicates a neutral solution, pH below 7 indicates an acidic solution, and pH above 7 indicates an alkaline or basic solution. The lower the pH value, the higher the acidity of the solution.
02

Determine the acidity of given pH values

We can now analyze each pH value and compare their acidity: (a) pH = 2 (b) pH = 4 (c) pH = 6 (d) pH = 8
03

Identify the strongest acid

According to the pH scale, the lower the pH value, the stronger the acidity. In our case, the lowest pH value is 2, which means that the strongest acid corresponds to option (a). So, the answer is (a) 2.
