WebOct 18, 2024 · HNO3 is a strong acid, so every single HNO3 molecule breaks apart into an H (+1) ion and an NO3 (-1) ion. This means 0.1 mol/L of HNO3 yields 0.1 mol/L of H (+1) ions. So the pH is -log... WebJun 19, 2024 · NH4Br is an acidic salt (from a strong acid and a weak base), so the pH should be <7. You have set it up correctly using the hydrolysis of NH4 + and the Ka for NH4 + (an acid). NH4 + + H2O ==> NH3 + H3O + (NH4OH + H+) Ka = [NH3] [H3O+]/ [NH4+] From pKa find Ka and solve for H3O+ Obtain pH as -log [H30+] Upvote • 0 Downvote Add … WebJan 31, 2016 · Hydrocloric acid is a strong acid, which means that it dissociates completely to form hydronium ions and chloride anions.
