Question

calculate the ph of a solution if h₃o⁺ = 1.0 x 10⁻⁷. 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 $[H_3O^+]=1.0\times 10^{-7}$, then $pH = -\log(1.0\times 10^{-7})$.
Since $\log(1.0\times 10^{-7})=- 7$, so $pH=-(-7)=7$.

Step3: Determine solution type

A solution with $pH = 7$ is neutral.

Answer:

$pH = 7$
NEUTRAL
