Question

what is the reaction between zinc metals with acid and base

Answer 1

•When an acid combines with metal it forms salt and release hydrogen gas

Metal + acid – metal salt + H2

2Na + H2Co3– Na2Co3+ H2


• When a base combine with metal it forms metal salt / base and release hydrogen gas

Base + metal – base/metals/salt + H2


2NaoH + Zn – Na2ZnO3+ H2(sodium Zincates)


There are two possible reaction of base with metal

only with zinc and aluminum

Answer 2

ZN + 2HCL ======> ZNCL2 +H2

ZN +H2SO4 ========> ZNSO4 +H2

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@


ZN + 2NAOH ========> NA2ZNO2 + H2

ZN + 2KOH =========> K2ZNO2 + H2
