When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate of come apart. The resulting dissolved ions are electrically charged particles that allow the solution to conduct electricity. The following chemical equations represent this phenomenon: NaCl (s) =
Na+ (aq) + Cl- (aq)
How do I write a similar balanced chemical equation for these electrolyte:
NaCl HCN HCl
Na2CO3
NaHCO
NH4Cl
NH3
