madhuri spilled lemon juice on marble floor her mother was panic why?
Answers
This is because marble is made of calcium carbonate and lemon juice is acidic in nature. This acid in lemon reacts with the calcium carbonate in marble and corrode the marble producing carbon dioxide.
When lemon juice will fall on marble floor, it will leave dull spots on the floor and leaves the marble textured. This is the reason why Madhuri's mother was worried.
Madhuri spilled lemon juice falls on marble floor her mother was panic because the following chemical reaction occurs :
Marble contains calcium carbonate and it reacts with lemon juice and produces white calcium citrate salt and a effervescence of liberation of CO2 gas .
The part of marble stone, where lemon juice spills turns to white .
chemical reaction :
Calcium carbonate + lemon juice ---> calcium citrate +CO2 gas
calcium citrate formed on tile leaves a white mark on tile which can be cleaned with water.
