Question

Identify the neutralization as well as precipitation reaction in the following – * a) Reaction between Carbonic Acid and Calcium Hydroxide b) Reaction between Copper Hydroxide andSulphuric Acid c) Reaction between Barium Nitrate and Calcium Sulphate d) Reaction between Ammonium Hydroxide and Hydrochloric Acid ko​

Answer 1

Answer:

1. Carbonic acid causes the acidity in fizzy drinks. Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate.
2. In neutralization reaction copper hydroxide a base reacts with sulphuric acid to form copper sulfate. It is a normal salt present in hydrated and anhydrous form. it gives salt.
3. In the reaction of calcium sulfate aqueous with barium nitrate aqueous produced barium sulfate as solid and calcium nitrate as aqueous state. ... In the reaction of calcium sulfate aqueous with barium nitrate aqueous produced barium sulfate as solid and calcium nitrate as aqueous state.
4. t’s a classic acid + alkali = salt + water reaction. The salt formed will be ammonium chloride. Hold concentrated hydrochloric acid next to a strong ammonium hydroxide solution and you’ll get clouds of smoke because in this case it’s two gasses reacting to produce a solid. Hydrogen chloride (from the acid) and ammonia (from the ammonium hydroxide) react together to make ammonium chloride (the white smoke). No water involved this time.
