Solution of copper (II) sulfate reacts with solution of sodium hydroxide to ____
Juli2301 [7.4K]

<u>Answer:</u>

A. Solution of copper (II) sulfate reacts with solution of sodium hydroxide to produce "copper hydroxide & solution of sodium sulphate".

B. Solid baking soda (sodium hydrogen carbonate or sodium bicarbonate) reacts with solution of hydrochloric acid to produce "carbon dioxide and water".

<u>Explanation:</u>

When CuSO4 is an acid salt while NaOH is a solid base mixed together. This reaction results into a basic copper hydroxide in the form of pale blue precipitate & sodium sulphate, which is a solution of neutral salt. This process is called as both a double displacement and precipitation reaction.

2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4.

Sodium bicarbonate is used as a cleaner, from a "primitive" material to extract any acidic contaminants, for producing a nobler sample. Sodium bicarbonate and acid mixture generates a salt and carbonic acid that breaks down readily into carbon dioxide and water.

NaHCO3 + HCl → NaCl + H2CO. H2CO3 → H2O + CO2(g).

Why a plant can survive longer than bacteria
Arlecino [84]

Answer:

Bacteria are vital in keeping nitrogen cycling through the ecosystem, and nitrogen is vital to plant growth. Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system
