Ocean water can be desalinated through the processes of reverse osmosis or heat distillation. Why don't we do this more often? Check all correct answers. It's expensive.

It uses a great deal of energy.

We would drain the oceans.

We don't know how

Hi + naoh -> h2o + nal

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
