As shown by the equations: H2O + HCO3− table_14.JPG H3O+ + CO32− H2O + HCO3− table_14.JPG H2CO3 + OH−
a)water is a base
b)water is an acid
c)water is amphoteric
d)water is neutral
H2O + HCO3− .............> H3O+ + CO32−
Water accepts the proton from HCo3- so it act as a base
H2O + HCO3− .............> H2CO3 + OH−
Water donates the proton to HCo3- so it act as a acid
A compound which act as both proton donor and acceptor is called amphotric. So water is amphotiric
answer C is correct
