3 Ways to Calculate pH - wikiHow

WebApr 4, 2024 · \[pH = - \log [{10^{ - 6}}]\] \[pH = 6\] The pH of \[{10^{ - 6}}M\] HCl (aq) is 6. So, the correct answer is “Option B”. Note: - We have to remember that pH and pOH are … Web1. Calculate the pH of a 0.00001 M HCl solution. 0.00001= 1 x 10 ^-5. Since HCl is an acid, 1 x10^-5 is the H+ concentration. Write only the number of the exponent. Therefore, pH = 5. 2. Calculate the pOH of a solution whose [OH-] is 2 x 10 ^-5. pOH = 4.7 3. Calculate the pH and pOH of a 0.0003 M solution of KOH.
