When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. Which property of water accounts for this occurrence

A) cohesion

B) pH

C) polarity

D) surface tension

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

  • In water molecules hydrogen bonds provides a special dipole - dipole attraction.
  • Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
  • This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
  • This makes the molecule of water polar.
  • By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.

The property of water that is at work as described in the question is polarity.

Water is composed of oppositely charged ends; a positive end and a negative end. These oppositely charged ends are called "dipoles".

The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.
