Question

Equal pieces of zinc granules are dropped in four test tubes. Following substances are poured in all the four test tubes. The reaction will be vigorous with
(a) acetic acid
(b) lemon juice
(c) hydrochloric acid
(d) none of these ​

Answer 1

Answer:

Explanation:

HCL is the answer because it is a strong acid

Answer 2

Option C is the correct answer.

• zinc metal reacts with acetic acid to build sodium acetate and hydrogen gas. Zinc is a strong metal that readily responds at room temperature.
• Zn atoms dissolve in the acidic citrus juice evacuating 2 negatively charged electrons (e-) backwards in the Zn anode. As Zn arrives at the solution, 2 positively charged H+ ions pick up 2 electrons at the Cu cathode and aspect H2 gas.
• When zinc reacts with hydrochloric acid it generates zinc chloride and hydrogen gas. We can estimate the rate of the outcome by assessing how fast the reaction generates hydrogen.

Hence, option C is the correct answer.
