Question

question 2 (multiple choice worth 2 points) (02.01r mc) which of the following best explains how water is able to dissolve ionic substances? the positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart. the strong hydrogen bond on water attracts the positive end of the ionic molecule and breaks the ionic bond. water acts as a proton donor for the negative end of the ionic molecule to attract the anion and form a new ionic molecule. the water molecule shares its electrons in a covalent bond with the positive end of the ionic molecule to break the ionic bond.

Explanation:

Water is a polar molecule with a partially positive end (hydrogen) and partially negative end (oxygen). When interacting with ionic substances (composed of positive cations and negative anions), the opposite charges attract: water's positive ends pull on anions, and negative ends pull on cations, overcoming the ionic bond and dissolving the substance. This matches the mechanism of hydration for ionic solutes.

Answer:

The positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart
