"Water is a polar solvent with a high dielectric solvent." Explain the statement.
Solution:
The solvent is the substance that dissolves another substance (called solute) in it.
A polar solvent is a solvent that dissolves polar solute in it (like dissolves like). Polar solutes are generally ionic compounds.
Polar solvents have molecules whose electric charges are unequally distributed, leaving one end of each molecule more positive than the other. Examples include water, alcohol (methanol, ethanol, etc), etc.
Water has a very high dielectric constant because the water molecule possesses dipole moment and so it can be polarized. That is, under a given electric field, water tends to polarize strongly, nearly canceling out the effect of the field.
