Reaction of acids with amphoteric oxides and hydroxides
Answer Text: Reaction of acids with amphoteric oxide and hydroxide- Oxides react with acids to form a salt and water only in a reaction called neutralization reaction.EquationsOxides:i)#PbO(s)+2H^(+)(aq) to Pb^(2+) + H_2O(l)#ii)#Al_2O_3(s)+6H^(+) to 2Al^(3+)(aq) +3H_2O(l)#iii)#ZnO(s) + 2HCl(aq) to ZnCl_2 (aq) +H_2O(l)#Hydroxides:i)#Pb(OH)_2(s)+2HCl(aq) to PbCl_2(aq) + 2H_2O(l)#ii)#Zn(OH)_2(s)+2HCl(aq) to ZnCl_2(aq) +2H_2O(l)#iii)#Al(OH)_3(s) + 3HCl (aq) to AlCl_3(aq) H_2(l)#Note: in these reactions the metal oxides are reacting as bases
