There are very few strong acids, so one of the easiest ways to tell strong and weak acids apart is to memorize the short list of strong ones. NH4OH - weak base. Write out HnXOm as Om-nX(OH)2 : ClO3(OH) O3 indicates an extremely strong acid; the formal charge on Cl is 3+ and this results in an extremely weak O-H bond and hence H^+ is easily ionized. As a part of this it defines and explains what is meant by pH, K a and pK a.. Lv 4. Memorize the short list of acids that are typically thought of as strong. Perchloric acid, strong acid.
