Which chemical equation represents a neutralisation reaction?
|
|
Mg + H2SO4
|
|
|
ZnCl2 + 2HNO3
|
|
|
2HCl + CaCO3
|
|
|
NaOH + CH3COOH
|
Explanation:
Detailed explanation-1: -This reaction is called neutralisation reaction. In this, acid is acetic acid and base is sodium hydroxide. Salt (CH3COONa) is formed.
Detailed explanation-2: -CH 3 COOH ( aq ) + NaOH ( aq ) → CH 3 COONa ( aq ) + H 2 O ( l )
Detailed explanation-3: -Answer: The chemical name of CH 3 COONa is sodium acetate. It is a sodium salt of acetic acid which upon dissociation releases a weak acid and a strong base.
Detailed explanation-4: -The correct answer is Alkaline. Explanation: Sodium acetate (CH3COONa) is the sodium salt of acetic acid. The neutralisation reaction between acetic acid (CH3COOH) and sodium hydroxide (NaOH) forms sodium acetate (CH3COONa).
