In this topic, we learnt how different substanes dissolve in one another.The topic consist of 3 parts: Introduction, Factors affecting Solubility and Comparison.
Solutions are the equivilant of Mixtures. A solution is formed when a solute dissolves in a solvent. A suspension is a failed solution. When the solute does not dissolve in the solvent or there is excess solute, the solution is called a suspension.
Solubility refers to the amount of solute that dissolves in the solvent. There 3 factors which affect the solubility and they are the type of solute, the temperature of the solvent and the type of solvent. Different solutes have different solubilities in the same solvents.One example is that sugar dissolves faster than chald powder in water. The temperature also affects the solubility as as the temperature of the solvent gets higher, most solutes become more soluble. Some solvents may also be more suitable for certain solutes although water is the most common solvent.
Solutions and Suspensions have different properties from one another. One difference is that solute particles in a solution do not rest at the bottom of the beaker but they do in suspensions.Particles in a solution can also pass through a filter paper while particles in a suspension cannot. Solutions are also clear and can be seen through while suspensions cannot. An example of a suspension is medicine.
Reflections: This topic teaches us about how some substances can dissolve in others while some can't. I feel that this topic is somewhat related to mixtures as they both have to do with mixing substances wth one another.
