The Reaction H2CO3 ? H+ + HCO3 is What Type

Question

The reaction H2CO3 ? H+ + HCO3 is what type of reaction?
A) decomposition
B) exchange
C) hydrolysis
D) synthesis
E) reversible

Accepted Answer

The given reaction is a reversible reaction, as it can occur in both forward and backward directions. In one direction, carbonic acid (H2CO3) can dissociate into hydrogen ions (H+) and bicarbonate ions (HCO3-), and in the other direction, bicarbonate ions and hydrogen ions can combine to form carbonic acid.
