Which of the following would NOT be a factor for a solute to dissolve in water?
A. A solute separates into ions which are supported by hydration.
B. Electrostatic attraction between the partially charged atoms in water molecules and the solute.
C. A solute has a higher formula weight than water.
D. A solute contains a molecular dipole.
E. All of these are factors.
i am pretty sure it is C but not positive.
See your post below.
To determine which of the options would NOT be a factor for a solute to dissolve in water, you need to evaluate each option and understand how it contributes to the dissolution process.
A. A solute separates into ions which are supported by hydration: When a solute dissolves in water, it may break down into its constituent ions, which are surrounded and stabilized by water molecules through a process called hydration. This aids in the solute's dissolution.
B. Electrostatic attraction between the partially charged atoms in water molecules and the solute: Water molecules are polar, meaning they have a partially positive end (hydrogen atoms) and a partially negative end (oxygen atom). This polarity allows for electrostatic attractions to form between the solute and water molecules, encouraging dissolution.
C. A solute has a higher formula weight than water: The formula weight or molecular weight of a substance is the sum of the atomic weights of all the atoms in a molecule. This option suggests that the solute has a higher molecular weight than water. While this information may affect the solute's overall properties, it does not directly determine its solubility in water.
D. A solute contains a molecular dipole: A molecular dipole is present when there is an uneven distribution of electron density within a molecule, resulting in a partially positive and partially negative end. This dipole can interact with water molecules through electrostatic attractions, facilitating dissolution.
Now that we have examined each option, we can conclude that option C, "A solute has a higher formula weight than water," would NOT be a direct factor for a solute to dissolve in water. The solubility of a substance mainly depends on its ability to form attractions with water molecules (hydration) and not on molecular weight alone. Therefore, the correct answer is C.
