Section D: Give a long answer to the question given below.
34b. An acid 'X' present in tamarind when mixed with 'Y', produces a mixture 'Z'. 'Z' in addition to a dough when heated makes cakes soft and spongy. 'Y' is prepared from common salt and helps in faster cooking.
(i). Write the common names of X', 'Y' and 'Z', and the chemical formula of Y.
(ii). How is 'Y' prepared and how does it help in making cakes soft and spongy? Illustrate the reaction with a suitable chemical equation.
(iii). Write the name and chemical formula of a mild base other than 'Y' used as an antacid.
(i). Write the common names of X', 'Y' and 'Z', and the chemical formula of Y.
(ii). How is 'Y' prepared and how does it help in making cakes soft and spongy? Illustrate the reaction with a suitable chemical equation.
(iii). Write the name and chemical formula of a mild base other than 'Y' used as an antacid.
(i). Acid 'X' present in tamarind - The acid commonly found in tamarind is .
'Y' is prepared from common salt and helps in faster cooking - This indicates that 'Y' is baking soda () prepared from common salt (sodium chloride).
'Z' makes cakes soft and spongy when added to dough and heated - This indicates that 'Z' is , which is a mixture of baking soda and an acid (often cream of tartar).
(ii). is prepared by reacting sodium chloride (common salt) with ammonia and carbon dioxide. It helps in making cakes soft and spongy by releasing carbon dioxide gas when heated, which gets trapped in the dough, causing it to rise.
The reaction is: \(NaCl\) + \(NH_3\) + \(CO_2\) + \(H_2O\) → \(NaHCO_3\) + \(NH_4Cl\)
(iii). is commonly used as a mild base in antacid formulations to neutralize stomach acid and relieve indigestion and heartburn.
