all 1 mark
b) in the following reaction, identify the reactant that acts as an acid:

c) identify the acid-base conjugate pairs in the following reactions:
HCO3- (aq) + H3O+ (aq) β-> <β- CO2 (g) + H2O + H2O (I). ( 2 marks )

Q1
(i) is an acid . It donates
(ii) is an acid. It donates
(ii) is basic.. Because it accepts
(b) HClO acts as acid . it donates H+
According to Bronsted- Lowry theory, acid are donors of protons and bases are acceptors of protons (H+)
is Bronsted Base, it accepts
is conjugate acid, it donates H+
