Question
complete the following paragraph to correctly describe how water associates in solution.
salt
due to waters ________, it is capable of dissolving a great number of substances.
water
a ______ contains a dissolved substance called a ______.
solution
in a mixture of salt water, ______ is the solute, ____ is the solvent, and ______ is the solution.
polarity
when salt is added to water, the ______ poles of the water molecules are attracted to the ____ sodium ions, and the ____ poles of the water molecule are attracted to the ______ chloride ions.
positive
the result is that the sodium and chloride ions ________ in water.
solute
negative
dissociate
salt water
First Blank:
Water's polarity (having a positive and negative end) allows it to dissolve many substances (like ionic compounds or polar molecules) due to electrostatic interactions. So the first blank is filled with "polarity".
Second and Third Blanks:
A solution is a homogeneous mixture where a solute (the dissolved substance) is dissolved in a solvent. So the second blank is "solution" (the mixture) and the third is "solute" (the dissolved part).
Fourth, Fifth, Sixth Blanks:
In salt water, salt is the solute (the substance being dissolved), water is the solvent (the dissolving medium), and salt water is the solution (the mixture). So the fourth blank: "salt", fifth: "water", sixth: "salt water".
Seventh, Eighth, Ninth, Tenth Blanks:

- Due to water's \boxed{polarity}, it is capable of dissolving a great number of substances.
- A \boxed{solution} contains a dissolved substance called a \boxed{solute}.
- In a mixture of salt water, \boxed{salt} is the solute, \boxed{water} is the solvent, and \boxed{salt water} is the solution.
- When salt is added to water, the \boxed{negative} poles of the water molecules are attracted to the \boxed{positive} sodium ions, and the \boxed{positive} poles of the water molecule are attracted to the \boxed{negative} chloride ions.
- The result is that the sodium and chloride ions \boxed{dissociate} in water.
