Question

To study the properties of acid (dilute hcl) by its reaction with : 1.Litmus solution (blue/red) , 2.Zinc metal , 3.Solid sodium carbonate

Answer 1

Answer:

Litmus solution

acids change blue litmus to red litmus.

Zinc metal

HCl acid reacts with zinc to produce ZnCl2 and H2 gas.

Zn(s) + 2HCl(aq) ➡ ZnCl2(s) + H2(g)

Solid sodium carbonate

HCl reacts with solid Na2CO3 to produce NaCl, CO2 and H2O

Na2CO3(s) + 2HCl(aq) ➡ 2NaCl(s) + CO2(g) + H2O(l)
