Match acids in column A with their sources in column B. 1. Column A Column B 2. Hydrochloric acid (a) citrus fruits 3. Oxalic acid (b) curd and sour milk 4. Tartaric acid (c) grapes, raw mango 5. Lactic acid (d) spinach 6. Ascorbic acid (e) In the stomach as gastric juice

The gastric glands of the stomach secrete gastric juice which is hydrochloric acid that helps body to digest and absorb nutrients such as protein. Spinach contains oxalic acid, an organic substance that can interfere with the absorption of essential nutrients like calcium and iron. Tartaric acid is a white crystalline organic acid that occurs naturally in many fruits, example: grapes and raw mango. Lactic acid is found in curd and sour milk. The bacteria lactobacillus reacts with milk sugars to produce lactic acid. Ascorbic acid is natural water-soluble vitamin. It is found in citrus fruits. Hence, the correct match is :- Column A Column B 1. Hydrochloric acid (e) In the stomach as gastric juice 2. Oxalic acid (d) spinach 3. Tartaric acid (c) grapes, raw mango 4. Lactic acid (b)curd and sour milk. 5. Ascorbic acid (a) citrus fruits
