Question

what are immisible liquids give 2 example ​

Answer 1

Answer:

2 liquids are said to be immiscible if they are completely insoluble in each otherSuch a system works in 2 phrases,throug it is ussually referred to as a mixture.

exampls:include benzene and water,kerosene in water etc.

hope it helps

pls thank my answer and

mark me as brainliest

Answer 2

IMMISIBLE LIQUIDS:In order for two liquids to mix, the energy to break the attraction between molecules within the liquids needs to be overcome by the energy released when the two liquids mix, known as enthalpy. Polarity in liquids commonly used as solvents is one property that can prevent mixing due to enthalpy. Polar liquids have molecules with positive and negative ends that attract to form strong intermolecular bonds. Non-polar liquids are held together by weaker van der Waals forces. Liquids with similar polarities are able to mix, but low-polarity molecules cannot overcome the strong bonds in a higher polarity liquid, so they remain separate.

EXAMPLES;

oil and water :

The classic example of immiscible liquids is oil and water. Water is very polar; the positive hydrogen end of the molecule forms especially strong hydrogen bonds with the negative oxygen end of another water molecule. Oil in this example can be any liquid fat or even motor oil. Oil is a non-polar molecule, so when you put the two liquids together, they do not mix. In addition to enthalpy, water is a special case where entropy also prevents mixing in what is known as the hydrophobic effect.

molten silver and lead

Not all examples of immiscible liquids are liquid at room temperature. For example, molten lead can only absorb 1.6 percent zinc and molten zinc can only absorb 1.2 percent lead, they are functionally immiscible. The difference between the Gibbs free energy, a measure of enthalpy related here to electronegativity, is what divides the metals. This particular set of immiscible liquids is important industrially because silver is much more miscible in zinc than lead, so zinc is used to extract silver from lead ores.
