a chemist is using a solution of hno3 that has a ph of 3.75. what is h+ for the solution? round to the nearest hundredth. × 10^n m n = done
Answer
Answer:
$1.78\times 10^{-4}\text{ M}$
Explanation:
Step1: Recall pH formula
$\text{pH}=-\log[\text{H}^+]$
Step2: Rearrange formula for [H+]
$[\text{H}^+]=10^{-\text{pH}}$
Step3: Substitute pH value
$[\text{H}^+]=10^{- 3.75}$
Step4: Calculate result
$[\text{H}^+]\approx1.78\times 10^{-4}\text{ M}$
