NaAlO2 and Na2ZnO2
formed which precipitate hence used for storing...these on dissolution give back NaOH

no both with metal and oxide it gives the aluminate and zincate because not only are the oxides amphoteric also the elements themselves are acids

the metals will themselves react.....Al,Zn,Sn...
but for some reason Sn is not used..
n if the metals do so will the oxides..as they form acidic oxides
