Hint: As we know that fizzing occurs in a chemical reaction due to the presence of a gas. Here, to identify the test tube in which fizzing occurs more vigorously, then we need to compare the acidity of both and .
Complete step by step answer:
According to question when equal lengths of magnesium ribbons are taken in test tubes A and B. Then, hydrochloric acid is added to test-tube A, while acetic acid is added to test tube B.
Thus, the reaction in test tube A is:
And the reaction in test tube B is:
It is evident that hydrogen gas is released in both the reactions. Though concentration of both the acids is same but we also know that hydrochloric acid is a stronger and reactive acid than acetic acid and therefore, the hydrogen gas produced in the reaction is at a faster rate due to which frizzing occurs in test tube A.
As is a stronger acid as compared to , magnesium metal is added to the chemical reaction. Thus, produces hydrogen gas due to which fizzing will be more vigorous in test-tube A.
So, the correct answer is Option A .
Note:
From the above question, we get to know that fizzing will occur more in test tube A because:
is a stronger acid whereas is a weaker acid.
Hydrochloric acid completely dissociates into and ions while doesn’t ionize completely.
