An aqueous solution at 25°C has a OH− concentration of 1.9x10−8M . Calculate the H3O+ concentration. Be sure your answer has the correct number of significant digits.
2 answers:
Answer : The concentration is,
Explanation:
First we have to calculate the pOH.
Given :
Concentration of =
Now we have to calculate the pH.
Now we have to calculate the concentration.
pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.
Formula used :
Therefore, the concentration is,
Answer:
= 5.26 × 10^-7 M
Explanation:
We know that;
[H3O+][OH-] = 1 x 10^-14
Therefore;
Given; OH− concentration = 1.9x10^−8 M
Then; [H3O+] = (1 x 10^-14)/[OH-]
= (1 x 10^-14)/(1.9x10^−8)
= 5.26 × 10^-7 M
