why tarnished copper vessels are cleaned with lime juice or tamarind

 Copper vessel gets tarnished due to copper oxide layer formed on its surface.Copper oxide is basic in nature.Lemon or tamarind is acidic.Hence, when we rub tarnished copper vessel with lemon juice or tamarind, the basic copper oxider reacts with acid(citric acid) present in the lemon or tamarind to form a salt which is washed away with water.Hence,the vessel gets cleaned.

 Tarnished copper vessels have a coat of copper carbonate.Lemon and tamarind are acidic in nature.These react with copper carbonate and help clean the vessels and bring back the shine.

C6H8O7 {citric acid }react with copper oxide { CUO}and forms a salt which gets cleaned by water.hence,vessels get cleaned
  • 4
Copper oxide, which is basic in nature, found on the surfaces of tarnished vessels gets neutralized by the acidity of the lemon/tamarind juice.
  • 4
And copper copper oxide layer is formed when lemon juice which contain citric acid is job on the copper utensils then it gets neutralized and the salt which formed on the surface of copper utensils get washed away
  • 3
Lemon juice contains citric acid and tamarind contains tartaric acid. These adds react with basic layer of copper carbonate on the surface to form soluble salts which are easily removed and surface shines.
  • 5
Copper oxide layer takes place on the surface of copper vessel and CuO is basic in nature and tamarind/lime juice is acidic in nature so when we clean copper vessel with tamarind juice neutralisation reaction takes place therefore, salt and water is formed. The water formed removes the salt and hence copper vessel is cleaned..

In tarnished copper vessel there is layer formed due to corrosion which is basic in nature which is dissolved in the lemon or tamarind juice which are acidic in nature. Thus the vessel get thoroughly cleaned.

Copper is tarnished i.e., it undergoes corrosion in presence of air.

Copper + Carbon dioxide + Water + Oxygen -> Copper Carbonate + Copper hydroxide

The nature of its corrosive substance is basic (basic copper carbonate). Thus substances of acidic behaviour are generally used to neutralize the basic nature and dissolve the corrosive layer of basic copper carbonate. This evinces a clean and shiny brown layer (original) of copper.

copper vessels get tarnished due to a layer called copper oxide which is basic in nature.the tamarind or the lemon juice which we use reacts and washes away with water.and hence gets cleaned

Because lemon juice are having critic acid with the help of citric acid we able to clean tarnished copper vessels so we using lemon and tamarind to clean tarnished copper Vessels


I hope it is helpful

The tarnished copper vessels have a layer of oxide of copper due to which it appears green.. Lime juice or tamarind has acid citric and tartaric acid respectively which on rubbing with oxide of copper neutralize its basic nature and hence the neutral salt is formed and the greenish layer is removed (metallic oxides r basic in nature)

Tarnished copper vessels are cleaned with tamarind as the nature of tarnished substance is basic.
When it cleaned with acid,it reacts it to form salt and water.and tarnished nature of copper vessels gets cleaned.
