Question

Madhuri spilled lemon juice on marble floor ? Her mother was panic why

Answer 1

Answer:

Mother is worried because spillage will produce C02.

Explanation:

White marble contains calcium carbonate CaCO3 and lemon contains ascorbic acid and citric acid.

Calcium carbonate readily reacts with ascorbic acid and citric acid to form calcium ascorbate and calcium citrate which are white (or colour less)

Also since baking soda is a base, while the lemon juice is an acid, when the two combine they create carbon dioxide (CO2). A high concentration can displace oxygen in the air. If less oxygen is available to breathe, symptoms such as rapid breathing, rapid heart rate, clumsiness, emotional upsets and fatigue can result.

Answer 2

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.
