Identify the type of interactions involved in each of the following processes taking place during the dissolution of sodium chlo
icang [17]

Answer:

A. Interactions between the ions of sodium chloride (solute-solute interactions).

B. Interactions involving dipole-dipole attractions (solvent-solvent interactions).

C. Interactions formed during hydration (solute-solvent interactions).

D. Interactions involving ion-ion attractions (solute-solute interactions).

E. Interactions associated with an exothermic process during the dissolution of sodium chloride (solute-solvent interactions).

F. Interactions between the water molecules (solvent-solvent interactions).

G. Interactions formed between the sodium ions and the oxygen atoms of water molecules (solute-solvent interactions).

Explanation:

The solution process takes place in three distinct  steps:  

  • Step 1 is the <u>separation of solvent molecules. </u>
  • Step 2 entails the <u>separation of solute molecules.</u>

These steps require energy input to break attractive intermolecular forces; therefore, <u>they are endothermic</u>.  

  • Step 3 refers to the <u>mixing of solvent and solute molecules.</u> This process can be <u>exothermic or endothermic</u>.

If the solute-solvent attraction is stronger than the solvent-solvent attraction and  solute-solute attraction, the solution process is favorable, or exothermic (ΔHsoln <  0).  If the solute-solvent interaction is weaker than the solvent-solvent and solute-solute  interactions, then the solution process is endothermic (ΔHsoln > 0).  

In the dissolution of sodium chloride, this process is exothermic.
