Question

Equal lengths of magnesium ribbon are taken in test tubes a and b hydrochloric acid is added to test tube a while acetic acid is added test tube b in which case the reaction would occur more vigorously and why ? Write the chemical equations for reactions in test tubes a and b

Answer 1

Explanation:

In HCL IT REACT VIGOROUSLY

BECAUSE IT IS STRONG ACID SO IT CAPABLE FOR MORE HYDROGEN GAS COMPARE ACETIC ACID

Mg+Hcl=Mgcl+Hydrogen

In acetic acid

CH3COOH+Mg=(CH3COOH)2 Mg+ Hydrogen

Answer 2

Answer:

please mark me as brainliest please

Fizzing will occur more vigorously in test tube A. Hydrochloric acid (HCl) is a strong acid whereas acetic acid (CH3COOH) is a weak acid. Being strong acid, the hydrochloric acid solution contains a much greater amount of hydrogen ions in it due to which the fizzing will occur more vigorously in test tube A (containing hydrochloric acid). The fizzing is due to the evolution of hydrogen gas which is formed by the action of acid on the magnesium metal of magnesium ribbon.
