Compared to aqueous solution of pH = 9, how many times the proton is concentrated in a solution of pH=6?

Explanation

To solve the problem of comparing the proton concentration in solutions of pH 9 and pH 6, follow these steps:

### Step 1: Understand the relationship between pH and proton concentration
The pH of a solution is related to the concentration of hydrogen ions (H⁺) by the formula:
\[ \text{pH} = -\log[\text{H}^+] \]
Where [H⁺] is the concentration of hydrogen ions in moles per liter (M).

### Step 2: Calculate the proton concentration for pH 9
