Question

calculate the ph of a solution if h₃o⁺ = 1.0 x 10⁻⁵. place a check mark on the correct solution type... ph = type acid neutral base

Explanation:

Step1: Recall pH formula

The formula for pH is $pH = -\log[H_3O^+]$.

Step2: Substitute the given value

Given $[H_3O^+]=1.0\times 10^{-5}$, then $pH = -\log(1.0\times 10^{-5})$.
Since $\log(1.0\times 10^{-5})=- 5$, so $pH = -(-5)=5$.

Step3: Determine solution type

A solution with $pH < 7$ is an acid. Since $pH = 5<7$, the solution is an acid.

Answer:

$pH = 5$
