Match the entries given in column A with appropriate ones from column B. $$ \begin{array}{lll} \hline \text { Column A } & \text { Column B } \\ \hline \text { A. } & \text { Sodium chloride } & \text { ( ) a. Baking powder } \\ \text { B. } & \text { Tartaric acid } & \text { () b. Freezing mixture in ice } \\\\\text { creams } \\ \text { C. } & \text { Potassium nitrate } & \text { () c. Antacid in medicine } \\ \text { D. } & \begin{array}{l} \text { Sodium } \\ \text { bicarbonate } \end{array} & \text { () d. Gun powder } \\ \text { E. } & \text { Citric acid } & \text { () e. Bleaching powder } \\ \text { F. } & \begin{array}{l} \text { Calcium } \\ \text { hydroxide } \end{array} & \text { () } f \text { . Flavouring agent } \\ \hline \end{array} $$

First, let's identify the correct use for each chemical listed in Column A: A. Sodium chloride - This is common table salt and is used as a freezing mixture in ice creams. B. Tartaric acid - Tartaric acid is used as a flavoring agent in food and beverages. C. Potassium nitrate - This chemical compound is an active ingredient in gunpowder. D. Sodium bicarbonate - Also known as baking soda, it is used as an antacid in medicine and as a leavening agent in baking powder. E. Citric acid - This weak organic acid is found in citrus fruits and is used as a flavoring agent in food and beverages. F. Calcium hydroxide - This inorganic compound is used in the production of bleaching powder.

Now, let's match the chemicals in Column A with their corresponding uses in Column B: A. Sodium chloride - (b) Freezing mixture in ice creams B. Tartaric acid - (f) Flavoring agent C. Potassium nitrate - (d) Gunpowder D. Sodium bicarbonate - (a) Baking powder and (c) Antacid in medicine E. Citric acid - (f) Flavoring agent F. Calcium hydroxide - (e) Bleaching powder The completed table will look like this: $$ \begin{array}{lll} \hline \text { Column A } & \text { Column B } \\\ \hline \text { A. } & \text { Sodium chloride } & (b) \text { Freezing mixture in ice creams } \\\ \text { B. } & \text { Tartaric acid } & (f) \text { Flavoring agent } \\\ \text { C. } & \text { Potassium nitrate } & (d) \text { Gun powder } \\\ \text { D. } & \begin{array}{l} \text { Sodium } \\\ \text { bicarbonate } \end{array} & (a) \text { Baking powder and } (c) \text { Antacid in medicine } \\\ \text { E. } & \text { Citric acid } & (f) \text { Flavoring agent } \\\ \text { F. } & \begin{array}{l} \text { Calcium } \\\ \text { hydroxide } \end{array} & (e) \text { Bleaching powder } \\\ \hline \end{array} $$
