This is to doing with my sience class exercise to doing with salts e.g. nitrates sulfates chlorides carbonates etc acid bases water acid + metal Hydrogen Acid +Carbonate etc the only part I can't remember are the neutalisation reactions can some one please help thank you.

You have to know that any acid reacting with a base is called an acid-base reaction, or neutralisation reaction.

If you have a know acid reacting with a substance producing water, then the other substance is automatically a base.

The same goes for an acid.

However, the real definition of an acid is:
An acid is a proton donor (provides H+ ions)
A base is a proton acceptor (takes H+ ions)

That's because you also have the base ammonia, NH3 and the gaseous hydrogen chloride acid HCl which take part in an acid-base reaction producing only ammonium chloride NH4Cl.
