Write a molecular, a complete, and a net ionic equation for the following reaction in aqueous solutions. All equations must be balanced.

Question

d. HBr(aq) and K2SO3(aq)

Answer 1

Balanced molecular equation:
2HBr(aq) + K2SO3(aq) ==> 2KBr(aq) + H2SO3(aq)
Balanced complete ionic equation:
2H^+(aq) + 2Br^-(aq) + 2K^+ + [SO3]^2-(aq) ==> 2K^+(aq) +2Br^-(aq) +
H2SO3(aq)
Note: Some may argue that H2SO3 should be written as SO2(aq) + H2O(l) and that H2SO3 doesn't exist but I assume this post is a general chemistry type question.
Net ionic equation:
2H^+(aq) + [SO3]^2-(aq) ==> H2SO3(aq)
