Q: What is the correct answer for CBSE10?

The correct answer is A. Hydrochloric acid (HCl) is a strong acid, meaning it dissociates completely in water to produce a high concentration of H⁺ ions. Acetic acid (CH₃COOH) is a weak acid, dissociating partially and producing fewer H⁺ ions. The rate of reaction with metal depends on the concentration of H⁺ ions. Therefore, fizzing (hydrogen gas evolution) will be more vigorous in test tube A with HCl.

The correct answer is A. Hydrochloric acid (HCl) is a strong acid, meaning it dissociates completely in water to produce a high concentration of H⁺ ions. Acetic acid (CH₃COOH) is a weak acid, dissociating partially and producing fewer H⁺ ions. The rate of reaction with metal depends on the concentration of H⁺ ions. Therefore, fizzing (hydrogen gas evolution) will be more vigorous in test tube A with HCl.

Q: What are the options for this CBSE10 question?

A. Test tube A, because HCl is a strong acid and produces more H⁺ ions. · B. Test tube B, because CH₃COOH is a weak acid and reacts slowly. · C. Fizzing will be equal in both, as concentrations are the same. · D. No fizzing will occur in either test tube.

Question

Equal lengths of magnesium ribbons are taken in test tubes A and B. HCl is added to A, and CH₃COOH is added to B. Both acids have the same amount and concentration. In which test tube will fizzing occur more vigorously and why?

FirstInTest · Accepted Answer

Hydrochloric acid (HCl) is a strong acid, meaning it dissociates completely in water to produce a high concentration of H⁺ ions. Acetic acid (CH₃COOH) is a weak acid, dissociating partially and producing fewer H⁺ ions. The rate of reaction with metal depends on the concentration of H⁺ ions. Therefore, fizzing (hydrogen gas evolution) will be more vigorous in test tube A with HCl.

Answer

Test tube A, because HCl is a strong acid and produces more H⁺ ions.

Answer

Test tube B, because CH₃COOH is a weak acid and reacts slowly.

Answer

Fizzing will be equal in both, as concentrations are the same.

Answer

No fizzing will occur in either test tube.
