Homework Answers
#1. Strong electrolytes - the substances which dissociates completely into the ions on adding water are called strong electrolytes .
e.g . HCl , NaOH etc .
Their dissociation in water is shown by forward arrow only .
HCl + water >>>>>>> H^+(aq) + Cl^-(aq) complete dissociates .
Weak electrolytes - are the substances which don't dissociates into ions completely on dissolving in water and they dissociates only partially in the constituting ions .
Their dissociation in water is shown by reversible arrows .
e.g . CH3COOH , NH4OH etc .
CH3COOH +water <<<<>>>> CH3COO^-(aq) + H^+(aq) partial dissociation in the ions .
