reaction...?

Question

Describe the type of reaction that occurs between certain metals and an acid.

Answer 1

Acid + metal ----> salt + hydrogen.

These reactions are always redox, but only work with metals that are above hydrogen in the reactivity series.

Answer 2

It will depend on the acid and the metal.
But a general over view is that metal's are not typically found in ionic form so they will usually react with oxygen or some other element. When an acid reacts with a metal it will strip the oxygen and replace the oxygen with an element from the acid.

The reaction will usually consist of heat and if done in test tube a change of color, bubbles, or if mixed with a compound it can not react with simply nothing.

Answer 3

It's an oxidation reduction reaction:

Sn(s) --> Sn+2(aq) + 2e-

2H+(aq) + 2e- --> H2(g)

overall and adding spectator ion

Sn(s) + 2HCl(aq) --> SnCl2(s) + H2(g)
