A student performs an experiment wherein he adds barium chloride to aluminium sulphate. Which of the following reaction is correct?​

Correct option is D

The correct answer is (d) 3BaCl₂(aq) + Al₂(SO₄)₃(aq) → 3BaSO₄(s) + 2AlCl₃(aq)

Explanation:

• Oxidation is the process where an element loses electrons. In this case, zinc (Zn) loses two electrons to form the zinc ion (Zn²⁺). This loss of electrons is what defines oxidation.

  ​$$\text{Zn} \rightarrow \text{Zn}^{2+} + 2e^-$$​​
  

• Hydrolysis refers to the reaction of a substance with water, typically resulting in the breakdown of a compound.

• Reduction is the process where an element gains electrons, which is the opposite of oxidation.

• Combination reaction involves two or more substances combining to form a single product, which is not applicable here.

Information Booster:​

• Oxidation: Loss of electrons; increases the oxidation state of an element.
• Reduction: Gain of electrons; decreases the oxidation state of an element.
• Hydrolysis: Reaction with water, often resulting in the breakdown of a compound.
