How do acids react with different metals under varying conditions?

Answer 1

Usually acids attack metals and oxidize them. Thus the metal atoms lose electrons, while the H+ ion from the acid gains an electron and forms H2 gas w/ another H atom. The metal ends up forming a salt w/ the anion that was part of the original acid. (i.e. Cl- from HCl).

This is a general statement. Some metals, don't react quickly to acid. Corrosion resistant steels have been engineered to resist acid attack. Gold is notorious for being resistant to acid attack except for Aqua Regia (water of kings) which is a mixture of nitric and hydrochloric acids.

Some acids are weak and this process is slow.

Heating usually speeds the oxidation process up. Sometimes this can be dramatic, as warm sulfuric acid is a very potent acid.

Again, all general. There are many metals and many acids which form alot of combinations.

Answer 2

this is because every metal has different properties and its due to that they react to different conditions differently.

for example, an element may react with air viglorously while the other may not - coz it depends on their chemical properties (remember air has oxygen, carbon dioxide etc. in it)
