Question

Write scientific reasons - Copper and brass vessels are cleaned with lemon.

Answer 1

Copper vessel gets flawed owing to the copper oxide layer created on its topmost surface.

Copper oxide is usually basic in nature. Tamarind or lemon is considered to be highly acidic.

Thus, when we rub the tarnished copper vessel with aid of tamarind or lemon juice, the copper oxide seems to react with the citric acid found in the tamarind or lemon to create a salt which is washed away easily with aid of water.

Answer 2

Answer:lemon juice has citric acid which etches away copper oxide that gives the vessels the dark colour

Explanation:metals like copper and brass gathers a copper oxide layer on the upper surface.

Lemon is considered to be very highly acidic in nature, as compared to copper.

So the lemon juice cleans and gives the vessels dark colour.
