which of the following best describes why ionic molecules dissolve and dissociate in water?
water is a polar, covalently bonded substance.
water is liquid at room temperature.
water is formed from nonpolar covalent bonds between oxygen and hydrogen.
water is hydrophobic.

Explanation:

Ionic molecules dissolve and dissociate in water because water is a polar, covalently - bonded substance. The polar nature of water allows it to interact with the charged ions in ionic compounds, pulling them apart and surrounding them. Water being liquid at room temperature is not the main reason for ionic compound dissolution. Water has polar covalent bonds, not non - polar ones, and it is hydrophilic, not hydrophobic.

Answer:

Water is a polar, covalently bonded substance.
