a salt is an ionic compound. So a metal + non-metal.

Basic reaction to form a salt : acid + base -> salt + water

Also OCR like the definition "when H+ in an acid has been replaced by a cation" eg HCl --> NaCl

Is that a good definition, because what about hydride salts, e.g. NaH, where the hydride is a H- ion, and the structure is just like an ionic lattice?

What he said, basically an end product of neutralisation

I see your point, however that's the exact definition the marking schemes want for OCR A a-level (see Jan 09 and Jan 10 F321) so if it's for an A-level paper then that's probably what the examiner is looking for.

By definition a salt is any chemical compound formed from an acid when the H+ ion from the acid is replaced by a metal ion or another positive ion, such as the ammonium NH4+ ion
