🤓 Based on our data, we think this question is relevant for Professor Pan's class at UA.
For the homogeneous solution, consisting of KCl and H2O, indicate the type of forces that are involved.
We’re being asked to identify the intermolecular forces present in the homogenous solution consisting of KCl and H2O.
Recall: Homogenous solutions have a uniform composition. It is composed of a solute that is completely soluble in a solvent.
This follows the rule "like dissolves like" where the solute and the solvent either have the same polarity or intermolecular force.
There are several types of intermolecular forces:
1. Ion-dipole interaction – occurs between an ion and a polar covalent compound
2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F
3. Dipole-dipole interaction – occurs between two polar covalent compounds
4. Induced-dipole interaction – occurs when a nonpolar compound interacts with a polar compound
5. Dispersion forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.
For this problem, we need to do the following steps to each compound:
Step 1: Determine the central atom in the molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Determine the polarity and IMF of the molecule.
Then, determine the intermolecular force between the two compounds.
