Which of the following is not an acid-base neutralization reaction?

A.) NH3 + HCl NH4Cl

B.) HCl + NaBr HBr + NaCl

C.) HCl + HBr H2 + ClBr

D.) 2 HBr + Ca (OH) 2 CaBr2 + 2 H2O

HCl + HBr H2 + ClBr is not acid and base reaction.

During electrolysis:

NH3 (g) + HCl (aq) = NH4Cl (aq) or

NH3 (g) + H3O + (aq) + Cl^1 - (aq) = NH4 + (aq) + Cl1 - (aq)

add OH1 - add H3O+

NH4OH + HCl

Hence,

The best answer is:

C.) HCl + HBr H2 + ClBr
