- 1Mixtures can be divided into 2 categories* Mixtures in which the composition is uniform throughout the mixture . Like, dissolving common salt in water
* Mixtures in which the composition is not uniform throughout the mixture . Like, dissolving clay in water - 2What are mixturesMatter which contains two or more substances which are not chemically combined, and can be separated by physical methods are called mixtures
- 3Homogeneous mixturesThe components cannot be observed separately from one another and the properties and composition are similar throughout the mixture
* Physical properties such as colour, transparency and density are identical everywhere
Eg - Salt solution, sugar solution - 4Heterogeneous mixturesThe components can be distinguished from one another and the physical properties such as colour and density differ from place to place
Eg - Clay dissolved in water, Cement mortar, Fruit salad - 5Solute and solvent of a solution* a solution compose on a solvent and one or more solutes
Solute + Solvent = Solution
Copper sulphate (solute) + Water (solvent) =Copper sulphate solution - 6Factors affecting solubility1. Temperature
2. Nature of the solute
3. Nature of the solvent - 7Solutes and solvents can be classified to 4 typesPolar organic solutes/solvents
Polar inorganic solutes/solvents
Non polar organic solutes/solvents
Non polar inorganic solutes/solvents - 8Polar solutes are soluble in polar solventsEthanol is a polar compound. Water is a polar compound. Therefor ethanol is soluble in water
Kerosene is a non polar solute. Water is a polar solvent. So kerosene is not soluble in water. - 9Non polar solutes are soluble in non polar solventsGrease is a non polar solute and kerosene is a non polar solvent. So grease is soluble in kerosene
Jak glue (Koholle) is a non polar solute and kerosene is a non polar solvent. So jak glue dissolves in kerosene
* Like dissolves in like but unlikely does not dissolve in like
