By Raj Vimal|Updated : October 10th, 2022

(A) Calcium Carbonate

(B) Sodium Chloride

(C) Lithium Bromide

(D) Magnesium Iodide

Calcium Carbonate is insoluble in water. The carbonic salt of calcium is calcium carbonate (CaCO ). The most widely used filler for PVC is calcium carbonate, called as chalk and mined as calcite. Because the electrostatic interactions between the calcium ion and the carbonate anion are too strong to be broken by solvation by water molecules, calcium carbonate is insoluble in water.

Why Does Calcium Carbonate Insoluble?

Calcium carbonate has very less solubility in pure water. However, it solubility increases with rainwater in the presence of Carbon Dioxide gas. It is an inorganic compound.

Sodium Chloride (NaCl): It is the chemical name for salt. Sodium is an electrolyte that regulates the water content in your body. Soluble in: Water, Methanol, Ammonia, Glycerol, Propylene glycol, Formic acid, and Formamide. 

Lithium Bromide (LiBr): It is a lithium salt with bromide as the counterion. Similar to common salt, anhydrous salt crystallizes into cubic shapes. It can be dissolved in ether, alcohol, and water. Lithium hydroxide is treated with hydrobromic acid to produce it.

Magnesium Iodide (MgI2): It is a typical ionic halide, being highly soluble in water.


Which of the following is Insoluble in Water? (A) Calcium Carbonate (B) Sodium Chloride (C) Lithium Bromide (D) Magnesium Iodide

Insoluble in water is calcium carbonate. It can be used in various ways such as personal health and food production and etc. Apart from this, making of baking powder, toothpaste, dry-mix dessert mixes, dough, and wine needs Calcium Carbonate.
