Question

calculate the ph of a solution if h₃o⁺ = 1.0×10⁻¹¹. place a check mark on the correct solution type... ph = 2 type acid neutral base

Explanation:

Step1: Recall pH formula

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

Step2: Substitute the given value

Given $[H_3O^+]=1.0\times 10^{-11}$, then $pH = -\log(1.0\times 10^{-11})$.
Since $\log(1.0\times 10^{-11})=- 11$, so $pH=-(-11)=11$.

Step3: Determine solution type

A solution with pH > 7 is a base.

Answer:

$pH = 11$, BASE
