Could someone explain to me how to prepare (a) zinc chloride by an acid-base reaction and (b) by a gas formation reaction. If the starting materials available are ZnCO3, HCL, CL2, HNO3, NaCL, Zn(NO3)2, and Zn.
Thanks so much for any info.
Zn + 2HCl ==> ZnCl2 + H2
H2 gas is evolved.
ZnCO3 + 2HCl ==> H2O + CO2 + ZnCl2
Both acid/base reaction AND CO2 gas is evolved.
