Chemistry define base
WebFor example, K 2 CO 3 is formed due to the acid-base reaction of potassium hydroxide (strong base) and H 2 CO 3 (weak acid). H 2 CO 3 + 2KOH → K 2 CO 3 + 2H 2 O. When a weak acid and weak base react with each other complete neutralisation does not occur due to incomplete ionisation of the acid and base. WebAdult Education. Basic Education.
