In which of the following, neutralisation reaction takes place?
1 Breakdown of glucose
2 Treatment of acidity
3 Photosynthesis
4 All of the above
Explanation:
Treatment of acidity Concept Applied: Neutralisation reaction happens between acid and base and salt is formed in the process. Explanation for correct option: To tread acidity, an antacid is used, which is an alkaline solution that neutralises the acid. Explanation for incorrect options: (A) Breakdown of glucose is metabolism. It is not a neutralisation reaction. (C) Photosynthesis is not a neutralisation reaction. It is a combination reaction. (D) Incorrect statement.
