What is `p^(H)` of the solution having H+ concntration 10^(-5)M

Answer

To find the pH of a solution with a hydrogen ion concentration of \(10^{-5}\) M, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the pH Definition**:
The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration \([H^+]\):
\[ \text{pH} = -\log[H^+] \]

2. **Identify the Given Concentration**:
We are given that the hydrogen ion concentration \([H^+]\) is \(10^{-5}\) M.

3. **Substitute the Concentration into the pH Formula**:
Plug the given concentration into the pH formula:
\[ \text{pH} = -\log(10^{-5}) \]

4. **Calculate the Logarithm**:
Using the properties of logarithms, we know that:
\[ \log(10^{-5}) = -5 \]
Therefore:
\[ \text{pH} = -(-5) = 5 \]

5. **Final Result**:
The pH of the solution is:
\[ \text{pH} = 5 \]

### Summary:
The pH of the solution with a hydrogen ion concentration of \(10^{-5}\) M is 5.
