When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate orcome apart. The resulting dissolved ions are electrically charged particles that allow the solution toconduct electricity. The following chemical equations represent this phenomenon:NaCl (s) → Na+ (aq) + Cl-(aq)Na2CO3 (s) → 2Na+(aq) + CO32- (aq)Write a similar balanced chemical equation for the other four strong electrolytes in the data table NaHCO3 KNO3NH4Cl HCl
