What happens to a piece of metal if you put it in an acid?

Answer 1

If you put a metal in an acid, the acid will take molecules or atoms away from the metal thus making the metal dissolve or seem to dissolve. It may not seem to dissolve if the acid is not strong enough to take away atoms or molecules. I learned this in my science class on Brainpop.com the video is called pH Scale if anyone wants to watch it.

Answer 2

The medal is oxidized (loses electrons) and becomes ionic in the water. On the other hand, the H+ from H2O becomes reduced (gains electrons) and synthesize to form Hydrogen gas (H2). The solution will begin to effervesce (bubbles) due to the escaping gas. This leaves the Hydroxide ion (OH-) in solution. When the Hydroxide ions are left in solution, the result is a basic solution.

Answer 3

The acid deprotonates in aqueous solution, and the negative ions induce nucleophilic attack on the positively-charged metal ions, removing metal ions from the metal and combining with them to form a salt.

The protons that dissociated into solution quite often recombine with each other to form diatomic hydrogen, which bubbles out of the solution as a gas.

This process of removing metal ions from the metal itself to be recombined into a salt with the original acid is called corrosion.

So, in a nutshell, the acid breaks down into ions, eats away bits of metal atoms from the original metal mass, combines into salt with the acid, and the hydrogen from the acid recombines to hydrogen gas, which bubbles out of the solution.

Answer 4

we will get a salt plus hydrogen gas. the formula eg. Al+Cl = AlCl3 ( Aluminium chloride or Aluminium trichloride ).
