Solution

Solution Steps

Step 1: Understanding pH and Acidity

The pH scale measures the acidity or basicity of a solution. It ranges from 0 to 14:

pH < 7: Acidic
pH = 7: Neutral
pH > 7: Basic

The lower the pH value, the stronger the acid. Conversely, the higher the pH value, the weaker the acid.

Step 2: Analyzing the Given pH Values

We need to determine which pH value corresponds to the weakest acid among the given options:

A) pH 8
B) pH 1
C) pH 7
D) pH 6
E) pH 14

Step 3: Identifying the Weakest Acid

Since acids have pH values less than 7, we can eliminate options A (pH 8) and E (pH 14) as they are basic. Among the remaining options (pH 1, pH 7, and pH 6), the weakest acid will have the highest pH value that is still less than 7.
