The statement "Water molecules are attracted by solute ions at the surface of the solute" is true about the dissolving process in water.
When a polar solute, such as salt (NaCl), is introduced to water, the polar water molecules interact with the charged ions of the solute. The partially positive hydrogen atoms in water are attracted to the negatively charged ions (anions), while the partially negative oxygen atoms are attracted to the positively charged ions (cations). This attraction helps to pull the solute ions away from the solid and into the solution, facilitating the dissolving process.
On the other hand, the statement "Polar solutes do not dissolve easily in water" is generally false. In fact, polar solutes typically dissolve well in water because they can interact favorably with the polar water molecules. Nonpolar solutes, in contrast, do not dissolve easily in water due to the lack of interaction between nonpolar molecules and polar water molecules.
