Question

2. Equal length of magnesium ribbon are taken in two test tubes ‘A’ and ‘B, H2SO4 is

added to test tube ‘A’ and CH3COOH in the test tube ‘B’ in equal amounts:
(a) Identify the test tube showing vigorous reaction.
(b) Give reason to support your answer.
(c) Out of the two acids taken above
(i) which one will have lower pH value.
(ii) lowerH+ concentration respectively

Answer 1

The answer to your question is below

Step-by-step explanation:

Data

Test tube 1 Test tube 2

Magnesium + Sulfuric acid Magnesium + Acetic acid

Mg + H₂SO₄ Mg + CH₃COOH

a) Test tube 1 will have a more vigorous reaction than test tube 2.

b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.

c)

i.- Sulfuric acid because is a strong acid

ii.- Acetic acid because is a weak acid.
