what is the hydronium ion concentration in a 0.55 M HNO3 solution ? what is the pH of this solution?

Question

Thank You!!!

Answer 1

HNO3 is a strong acid that ionizes 100%; therefore, 0.55M HNO3 has (H3O^+) = 0.55 M.
Then pH = -log(H3O^+)

Answer 2

Thank you !!

Answer 3

0.20 M HNO3

Answer 4

Calculate the hydroxide ion concentration of the following solution 0.20 M HNO3
