Strong and Weak Acids and Bases The strength of any acid depends upon the extent to which it gives hydrogen ions in solution. If the concentration of H + ions in a solution is high the acid is said to be strong. e.g. HCl, H 2 SO 4 , HNO 3 etc. If the concentration of H + ions in a solution is low the acid is said to be weak. e.g. Oxalic, tartaric, H 2 CO 3 etc. Similarly, strong bases are those, which when dissolved in water, readily give OH - ions. e.g. NaOH, KOH On the other hand, weak bases are those which when dissolved in
