Question

Equal lenth of maggnisium ribben are taken in two test tubes A and B\ H2SO4 is added to test tube A and H2CO3 in the test tube B in equal amounts: (a) identify the test tube showing vigorous reaction. (b) Give reason to support your answer. (c) Name the gas liberated in both the tubes. How will you prove the liberation? (d) write the chemical equations of both reactions. (e) out of the two acids taken above: (1) which one have lower pH value. (2) lowerH+ concentration respectively

Answer 1

Answer:

1.testube A show vigorous reaction

2.hydrogen gas elaborate in both reaction.

3.

mg+H2SO4------->MgSO4+H2

mg+H2Co3----->MgCO3 +H2.
