Answer:
10.3
Explanation:
The pH of a substance is a number spanning from 0 to 14.
A substance with pH between 0 and 7 is said to be acid, while a substance with pH between 7 and 14 is said to be basic. A substance with pH of 7 is a neutral substance.
The pH of a solution can be calculated using the formula:
[tex]pH=-log[H_3O^+][/tex]
where
[tex][H_3O^+][/tex] is the concentration of hydronium ion in the solution
In this problem, we have a concentration of hydronium ion in the solution equal to
[tex][H_3O^+]=4.7\cdot 10^{-11} mol/L[/tex]
Therefore, we can apply the formula above to calculate the pH of the solution, and we find:
[tex]pH=-log[4.7\cdot 10^{-11}]=10.3[/tex]
So, the pH of this solution is 10.3.
Answer:
This is formula to find pH. -log[H^+]
now press calculator -log[4.7×10^11] and you will get 10.33
