Solubility is the ability for a solute to dissolve into a solvent. Not all matter is created equal! What determines if a solute is soluble in a solvent is based on its particles. If particles of two substances are attracted to each other, a solution can be formed. For example, sugar is soluble in water. Their particles have attraction. If the particles are NOT attracted to each other, they are insoluble.
When we sunk the sugar cube into the flask of water, it took some time to dissolve. Some of us became impatient and our instinct was to shake or swirl the flask to get the sugar moving in the water. This works because the particles have an opportunity to move around and water particles can find sugar particles and make bonds much quicker. Another way to increase this RATE OF DISSOLVING is by adding heat! Remember that heat adds energy to the particles which make them move more, creating more space between particles, causing convection to occur thus moving particles of solute around with solvent.... increasing the chances of these particles forming bonds together to make that homogenous solution!
The following video is a short reinforcement of the concept of solubility and how heat can affect the rate of dissolving. They use the word "Disassociation" a few times which means when the salt particle separates or "disassociates" from other parts of the salt.
