Description : The main use of salt in the diet is to - (1) increase the solubility of the food particles in water. (2) produce in small amounts the hydrochloric acid required for the digestion of food (3) ease the process of cooking (4) make the taste of the food better
Last Answer : (2) produce in small amounts the hydrochloric acid required for the digestion of food Explanation: Salt plays a primary role in the processes of digestion and absorption. Salt activates ... hydrochloric acid. Hydrochloric acid is a very important digestive secretion, which lines the stomach walls.
Description : Metallic oxides which react with both acid and base to produce salt and water are called A) Neutral Oxides B) Basic Oxides C) Amphoteric Oxides D) Acidic Oxides
Last Answer : C) Amphoteric Oxides

Description : In an acid base reaction which product is produced along with a salt? (1) Hydrogen gas (2) Oxygen gas (3) Carbon dioxide (4) Water
Last Answer : (4) Water Explanation: When an acid and a base are placed together, they read to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water.
Description : The reaction between an acid and a base to give a salt and water is known as a - (1) Neutralisation reaction (2) Reduction reaction (3) Oxidation reaction (4) Exothermic reaction
Last Answer : (1) Neutralisation reaction Explanation: The effect of a base is nullified by an acid and vice-versa. Example: Reaction of Sodium hydroxide with hydrochloric acidNaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
Description : Which of the following chemical reactions does not lead to formation of a salt? w) Reaction of salts with acids. x) The reaction of base anhydrides with acid anhydrides. y) Action of water on oxides of nonmetals. z) Reaction of acid with base.
Last Answer : ANSWER: Y -- ACTION OF WATER ON OXIDES OF NONMETALS. (If water reacts with oxides of nonmetals, an acid is formed.)
Description : Which reaction does not yield an ester as one of the products? (a) A carboxylic acid is heated with an alcohol (b) A Grignard reagent is added to a carboxylic acid (c) An acid halide is treated with an alcohol (d) An alkyl halide is heated with the salt of a carboxylic acid
Last Answer : A Grignard reagent is added to a carboxylic acid
Last Answer : Alkali reacts with acid to produce salt and water

Description : What purpose does FeCl3 serve in the electrophilic aromatic substitution reaction between chlorine and benzene? (a) It serves as a radical initiator to produce the chlorine radical needed to propagate the ... by reacting with the Cl2 and thereby activates it toward attack by benzene's π electrons.
Last Answer : It serves as a Lewis acid catalyst by reacting with the Cl2 and thereby activates it toward attack by benzene’s π electrons.
