Identify the type of interactions involved in each of the following processes taking place during the dissolution of sodium chloride (NaCl) in water. Solvent-solvent interactions Solute-solute interactions Solute-solvent interactions

Solvent-Solvent interactions:

The existing bonding or interactions between the molecules of water are a dipole-dipole interaction. When NaCl solutes are dissolve in water it disturbs this existing dipole-dipole bond between the molecules of water.

Solute-Solute interactions: the solute-solute interaction is bond between molecules of the solute NaCl, NaCl is an ionic compound so the existing interaction between NaCl is ion-ion (NA+Cl-) interaction. When dissolved in water, the molecules of water tends to break this ion-ion interaction of NaCl.

Solute-Solvent interactions: this is the interaction that results to dissociation of NaCl. When NaCl is dissolved in H2O the ion-ion interaction of NaCl is broken, the molecules of the solvent interact with the molecules of the solute. This forms interactions between Na + and O-, and interaction between H + and Cl-
