what happens when an acid reacts with a metal?

Answer 1

zn + 2hcl - zncl2 + h2
metals react fast and tthey will form sulphates,chlorides acording to the acids used and the elements.cu cannot displsce H2 from h2so4 as it is less than H in halogen series

Answer 2

Depends on the type of acid ... not all acids are strong enough to burn holes through metal rapidly. Hydrochloric and sulfuric acids will work much faster than acetic and ascorbic acids due to their lower pH values based on reactivity of the acid due to their H-bondng properties (negative logarithms of H-ion concentration).

Generally though, the acid will give up hydrogen atoms since they are bonded weakly within the molecule. The metal will pick up the hydrogen atoms, which causes a breakdown in the molecular matrix, thus resulting in the metal being "eaten" or "burned" away by acid.

Answer 3

As a general rule hydrogen gas is given off and the solution of the metallic salt of the acid is left behind.

Depending upon the reactivity of the metal and the strength of the acid, the reaction may be slow eg lead.corrosion by acid rain, or it can be explosive eg sodium and hydrochloric acid .

Answer 4

When acid reacts with a metal Hydrogen gas is liberated and the metal is converted in to a salt.

For example reaction of copper with hydrochloric acid gives hydrogen gas and copper chloride. using sulphuric acid instead would give copper sulphate.

Answer 5

Acid + metal = salt + hydrogen.
eg magnesium and hydrochloric acid:
2 HCl + Mg = MgCl2 + H2

Answer 6

Me + HA >>>> MeA + H2

Answer 7

hydrogen gas is evolved.

Answer 8

it reacts fast!
