Which of the following salt is basic in nature?a)Aluminium chlorideb)Sodium acetatec)Sodium chlorided)Potassium nitrateCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

The anion is a conjugate base of a weak acid therefore a soluble acetate salt such as sodium acetate will release acetate ions into the solution which a few of These will interact with  water  forming unionized Acetic Acid And Hydroxide Ion

Answer

Sodium acetate is correct answer because it is the salt prepared by the reaction between a strong base that is NaOH and a weak acid CH3COOH and as we know that the salt of strong base and weak acid is basic in nature.hope help u.

Answer

Sodium acetate (CH₃COONa) is a salt in solid state and can't be regarded as an acid or base in anhydrous or molten form.
Although, being an ionic compound, sodium acetate dissociates in water to produce sodium ion Na+ and acetate ion CH₃COO^-. These ions react with water producing NaOH and CH₃COOH.
Now, as NaOH is a strong base and CH₃COOH is a weak acid, the resultant solution is basic in nature.
Hence, sodium acetate is basic in aqueous medium.

Answer

Correct answer B

Answer

Sodium acetate (option B) is the salt that is basic in nature.

Explanation:
To determine whether a salt is acidic, basic, or neutral in nature, we need to consider the nature of the ions present in the salt.

Sodium acetate (CH3COONa) consists of sodium ions (Na+) and acetate ions (CH3COO-).

Acetate ions (CH3COO-) are the conjugate base of acetic acid (CH3COOH). Acetate ions can accept a proton (H+) from water, making the solution basic. This reaction can be represented as:

CH3COO- + H2O ⇌ CH3COOH + OH-

The hydroxide ions (OH-) produced in the above reaction make the solution basic. Therefore, sodium acetate is basic in nature.

Comparison with other options:
- Aluminium chloride (option A) is a salt that consists of aluminium ions (Al3+) and chloride ions (Cl-). Neither of these ions has basic properties. Therefore, aluminium chloride is not basic.
- Sodium chloride (option C) is a salt that consists of sodium ions (Na+) and chloride ions (Cl-). Neither of these ions has basic properties. Therefore, sodium chloride is not basic.
- Potassium nitrate (option D) is a salt that consists of potassium ions (K+) and nitrate ions (NO3-). Neither of these ions has basic properties. Therefore, potassium nitrate is not basic.

Hence, among the given options, only sodium acetate (option B) is basic in nature.
