To enhance NaCl dissolution, consider the following actions: 1) Heat the mixture; 2) Add more water to the solution. Explanation: When sodium chloride dissolves in water, polar water molecules infiltrate the lattice of ions, attaching to negative chloride and positive sodium ions and pulling them into the solution, a process known as dissociation. Heating the solution accelerates dissociation, whereas more water added without heating lessens saturation, promoting further NaCl dissolution.
