Question:
Before tackling this problem, be sure you know how to find the antilog of a number using a scientific calculator.
A solution has a pH of 5.4. Write the formula you will use to calculate the [H+] and then show all your work leading to the determination of [H+].
ANSWER:
3.98*10^-6 mol dm-3
Step-by-step explanation:
pH= -log[H+]
-pH=log[H+]
[H+]= antilog -pH
[H+]=10^-5*4
[H+]=3.98*10-6 mol dm^-3
Hope this helps :)
