Correct option is C
The Correct Answer is: (c) Salt and water
Explanation:
When an acid reacts with a base, it is called a neutralisation reaction. In this chemical reaction, the H⁺ ions from the acid react with the OH⁻ ions from the base to form water (H₂O), and the remaining ions form a salt.
When an acid reacts with a base, it is called a neutralisation reaction. In this chemical reaction, the H⁺ ions from the acid react with the OH⁻ ions from the base to form water (H₂O), and the remaining ions form a salt.
General reaction:
Acid+Base→Salt+Water\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}Acid +Base →Salt +Water
Example:
HCl+NaOH→NaCl+H₂O\text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H₂O}HCl +NaOH →NaCl+ H₂O
This type of reaction is exothermic, meaning it releases heat.
Information Booster:
This is a double displacement reaction.
The pH of the solution moves toward 7 (neutral) as acid and base cancel each other.
Salt formed can be neutral, acidic, or basic depending on the strength of the acid and base.
Common acids: HCl, H₂SO₄, HNO₃; Common bases: NaOH, KOH, Ca(OH)₂.
The reaction is used in antacids, soil treatment, and wastewater treatment.
