Answer to Question #120275 in General Chemistry for queen

Question

What is the net ionic equation and the spectator ions for the reaction of solid zinc with hydrobromic acid?

Answer 1

reaction of Zn with HBr

Zn(s)+2HBr(aq)---->ZnBr₂(aq)+H₂(g)

ionic equations

Zn----->Zn²⁺+2e^-

2H⁺+2e^- ------>H₂

net ionic equations is

Zn+2H⁺----->Zn²⁺+H₂

spectator ion is an ion that exists as a reactant and a product in a chemical equation.

so here Br^- is spectator ion
