 *  media type="file" key="Solubility(2).mov" width="300" height="300"To understand how pressure, type of solvent, and temperature affect the solubility of a substance, you have to know what solubility is. Solubility is the measure of how much solute can be dissolved in a solvent. Now for pressure. Pressure affects only gas, not liquid and solid. When you add pressure to a gas, the gas molecules are forced in to the solution. This means the solubility rises when pressure is added. What about type of solvent you ask? Well when you have different solvents the reaction of each one is different. Even if you have the same solute, the solubility will be different between each one. Let me show you some examples of different solvents that make the solubility measure change. The solubility of sugar poured in to water is high, but the solubility of Barium sulfate poured in to water is low. Now comes temperature. When temperature increase is added to liquid water, the solubility of the substance is increases. The warm temperature makes the solute dissolve much faster than a cold temperature. When the temperature decreases the solubility goes down. Finally stirring a solution. When you stir a solute in a solvent the solubility can either be high or low. It depends on the temperature, if it is hot or warmer, stirring progresses the solubility. If the temperature is cold or cool, stirring will make no impact on the solubility. Now you know that you’ll make a hundred on question about solubility! **
