Further Acid Reactions

Question 1

What are the possible acid reactions?

Answer 1

An acid and base, acid and metal

Question 2

What two products are there when acid and metal react?

Answer 2

Metal salt (MgCl2) and hydrogen (H2)

Question 3

How do we know that hydrogen gas has been produced?

Answer 3

A pop test is used to determine if hydrogen gas has been produced. When reacting an acid and metal, hydrogen gas is produced. When a lit match comes close, the collision of the hydrogen and oxygen combine to make water. Makes a POP! sound.

Question 4

Do all metals react with acid?

Answer 4

Most do but not all. The reactivity of metals is in the formula sheet.

Question 5

What 3 products do acids and carbonates create?

Answer 5

Water (H2O), Metal Salt (NaCl) and Carbon Dioxide (CO2)

Question 6

How do we know that CO2 was produced?

Answer 6

We know that CO2 was produced through the lit splint test. An acid and a carbonate are mixed and the gas produced is collected by a test tube placed on top.
A flame needs oxygen to burn but the oxygen is bonded to the carbon. This will force the flame to go out.
