Equal lengths of magnesium ribbon are taken in two test tubes $A$ and $B$. $H_{2}SO_{4}$ is added to test tube $A$ and $H_{2}CO_{3}$ in 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 test tubes. How will you prove its liberation?

$(b)$ Give reason to support your answer.
$(c)$ Name the gas liberated in both the test tubes. How will you prove its liberation?
(A) Vigorous reaction will be seen in test tube $A$.
$(b)$ This is because $H_{2}SO_{4}$ is a strong acid,whereas $H_{2}CO_{3}$ is a weak acid.
$(c)$ $(i)$ Hydrogen gas $(H_{2})$ is liberated in both test tubes.
$(ii)$ When a burning candle is brought near the evolving gas,it burns with a 'pop' sound. This confirms the presence of hydrogen gas.
