what is the ph of a solution of h2so4 that has h3o+=5.45×10−5 m? round to the nearest hundredth.
what is the ph of a solution of h2so4 that has h3o+=5.45×10−5 m? round to the nearest hundredth.
Answer
Answer:
4.26
Explanation:
Step1: Recall pH formula
$pH = -\log[H_3O^+]$
Step2: Substitute the given value
$pH=-\log(5.45\times 10^{-5})$
Step3: Calculate the result
$pH = 4.26$
