When sodium chloride, NaCl, is added to water, it forms a solution.
Rank the steps involved in the dissolution of salt in water from first step to last step. To rank items as equivalent, overlap them.
a.) NaCl crystal is added to water
b.) NaCl solution
c.) The Na ions are attracted to the water molecules
d.) The Cl ions are attracted to the water molecules

However, I prefer to say the water molecules are attracted to the Na ions (of the crystal) and Cl ions (of the crystal).

2.C&D
3.B
The correct sequence of steps involved in the dissolution of salt in water is as follows:
1) NaCl crystal is added to water (a.)
2) The Na ions are attracted to the water molecules (c.)
3) The Cl ions are attracted to the water molecules (d.)
4) NaCl solution (b.)
To rank the steps involved in the dissolution of salt in water, we need to understand the process of how the NaCl crystal dissolves in water:
1) NaCl crystal is added to water (a) - This is the first step where the solid NaCl crystal is introduced to the water.
2) The Na ions are attracted to the water molecules (c) - As the NaCl crystal comes into contact with water, the polar water molecules attract the sodium (Na+) ions, separating them from the chloride (Cl-) ions.
3) The Cl ions are attracted to the water molecules (d) - Similarly, the chloride (Cl-) ions are also attracted to the polar water molecules, creating a shell around them.
4) NaCl solution (b) - The result of the aforementioned steps is a NaCl solution, where the Na+ and Cl- ions become dispersed and surrounded by water molecules.
So, the correct ranking would be:
1. (a) NaCl crystal is added to water
2. (c) The Na ions are attracted to the water molecules
3. (d) The Cl ions are attracted to the water molecules
4. (b) NaCl solution
