Question 3 • TX-Chemistry B-CR

Which is most likely true about water in chemical systems?

Answer
A
Water dissolves nonpolar ionic compounds.
B
Water dissociates ionic compounds.
C
Water dissociates covalent molecules.
D
Water dissolves nonpolar covalent substances.

Explanation

Water is polar, so its partially charged ends attract the positive and negative ions in many ionic compounds. These attractions can pull the ions apart and surround them in solution; this is dissociation. Nonpolar substances generally do not dissolve well in water, and covalent molecules do not usually dissociate into ions simply because they are placed in water.
