Answer 1

Hint:The acid present in orange is vitamin C. It is soluble in water. Its deficiency causes scurvy. Vitamin C works against bacterial infection. It is an anti-oxidizing agent. The molecular formula of the acid or vitamin is ${{\text{C}}_{\text{6}}}{{\text{H}}_{\text{8}}}{{\text{O}}_{\text{6}}}$.

Complete answer:
A molecule that can donate a proton or accept electrons is known as acid.
Name of some of the natural acids and structures are as follows: Oxalic acid, maleic acid, succinic acid, lactic acid, tartaric acid.

1. Acetic acid is found in vinegar.
2. Oxalic and citric acids are found in tomatoes.
3. Ascorbic acid is found in an orange.
4. Citric acid is found in lemon.
5. Lactic acid is found in curd.

7. Tartaric acid is found in tamarind.
So, the acid present in orange is ascorbic. Ascorbic acid is found in citrus fruits and green vegetables.
The structure of ascorbic acid is as follows:

Note:
All acids have two carboxylic groups. The substance which has acids has a sour test. The pH of the juice of these substances will be less than seven. Juice of these substances can convert blue litmus into red which confirms the acidic nature of these substances. Ascorbic acid or vitamin C cannot be produced by the body and cannot be stored. It is obtained from the diet. It is necessary for the recovery of the tissues. Fruit and vegetables are rich sources of ascorbic acid.
