Question

if \\(\text{h}^+ = 0.0001\text{ m}\\), then \\(\text{ph} = \\)

4 3 2 1

Explanation:

State the pH formula

$$ \text{pH} = -\log_{10}[\text{H}^+] $$

Substitute the given concentration

$$ [\text{H}^+] = 0.0001\text{ M} = 10^{-4}\text{ M} $$

Calculate the final pH value

$$ \text{pH} = -\log_{10}(10^{-4}) = -(-4) = 4 $$

Answer:

If \([\text{H}^+] = 0.0001\text{ M}\), then \(\text{pH} =\) <blank>4</blank>.
