Description : Milk of magnesia is an example of a/an (1) Acid (2) Base (3) Salt (4) None of the above
Last Answer : (2) Base Explanation: Milk of Magnesia or Magnesium hydrozide is a base and an antacid. During indigestion, the stomach produces too much acid and this causes pain and irritation. To get rid of this pain, people use bases called antacids.
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 : Study the following table and choose the correct option: Salt - Parent Acid - Parent Base - Nature of Salt (a) Soidum Chloride - HCI - NaOH - Basic (b) Sodium Carbonate - H2CO3 - NaOH - Neutral (c) Sodium Sulphate - H2SO4 - NaOH - Acidic (d) Sodium Acetate - CH3COOH - NaOH - Basic
Last Answer : Answer: (d) Sodium Acetate - CH3COOH - NaOH - Basic
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
