Question

Which of the following is an acid-base neutralization reaction?

A. Sn+2HBr——>SnBr2+H2
B. HCL+KOH——-> KCL+H2O
C. 2AlCl3+ 3Ca(OH)2——> 2Al(OH)3+ 3CaCl2
D. 2C2H6+7O2—->4CO2+ 6H2O

Answer 1

In addition to the upper answer always notice H2O OH and H+ in acid base reactions

Answer 2

Only one equation here has an acid and a base as reactants.

B. HCL + KOH——-> KCL+H2O

acid base

So, this is an acid-base neutralization reaction.
