Generally, organic solvents are suitable in
dissolving organic solutes. Fats, oil, paints and
wax are organic compounds, and such organic
solvents as: tetrachloromethane; benzene;
diethylether; and alcohol are well known for
dissolving them.
Kerosene (also called paraffin) and petrol (also
called gasoline) may be used also. Removal of
stains – stains of organic compounds, such as
grease and oil on fabric can be removed by
applying any suitable organic solvent, such as any
of the above.
Kerosene is a hydrocarbon obtained from fractional distillation of coal tar. Hence, it is a hydrocarbon and hydrocarbon are non-polar solvents. Non-polar solvent dissolve only non-polar compounds. Oil and fat is an example of non-polar compounds.
The answer is B. Reason:calcium hydroxide is alkaline.lipids are nonpolar $ wil only dissolve in nonpolar solvent.
The correct answer is C. Kerosene.
Here's why:
* "Like dissolves like" A general rule in chemistry is that polar substances dissolve other polar substances, and nonpolar substances dissolve nonpolar substances.
* Fat: Fats are nonpolar molecules. This means they have an even distribution of electrons and no significant positive or negative charges.
* Kerosene: Kerosene is a nonpolar hydrocarbon liquid. Its nonpolar nature allows it to effectively dissolve fats and oils.
Let's look at the other options:
* A. Hydrochloric acid (HCl): This is a strong acid and a polar substance. It wouldn't dissolve fat effectively.
* B. Calcium hydroxide (Ca(OH)₂): This is a base and a polar substance. It wouldn't be effective in dissolving fat.
* D. Water (H₂O): Water is a polar molecule. While it can dissolve some polar molecules, it's not good at dissolving nonpolar substances like fats. That's why you see oil and water separate.
