Question

HBr + KOH mc001-1.jpg KBr + H2O In this reaction, the acid is

Answer 1

In the reaction, it can be seen that the H+ of the compound HBr was removed and replaced with K, making it KBr. Also, the OH- of KOH was removed and replaced. An acid is described as a compound that is capable of releasing H+. Thus, the answer is HBr. 

Answer 2

In the given chemical reaction, hydrogen bromide is an acid and potassium hydroxide is a base.

What are acids?

According to the Arrhenius theory, acids are those substances which will gives H⁺ to the aqueous solution and base will loses hydroxide ion.

Given chemical reaction is:
HBr + KOH → KBr + H₂O

In the above reaction HBr loses H⁺ ion in the solution and combines with potassium to form KBr salt. So, in the above equation HBr is an acid and KOH is a base.

Hence HBr is an acid.
