Answer #1

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

Hard/ Soft water: Why is CaCO3 present in hot water, but not in cold? My prfoessor talked about he has his water softerner only for hot water, but the cold water is not passed through a water softner. Can you please explain showing step by step equilibrium reactions and where the equilibrium is favored. Here are a few equations that might help your thought process. I guess I would just like an explaination as to why hot vs cold and...
