Grade 7

• Solution


  a specific type of mixture where one dissolve the other and it has a homogenous mixture.
• two parts of solution

  solue, solvent
• solute


  substance dissolved by another substance
• solvent


  substance that dissolves the other substance
• dissolving


  a process when large crystal of molecules breaks into smaller molecules
• solubility


  how much solute can be dissolve into a liter of solvent
• saturated


  a solution in which maximum amount of solvent has been dissolved
• concentration


  proportion of the solute to the solvent and measure if there is a lot of solute in a solution
• diluted


  low amount of solute
• two forms of liquid solution

  miscible, immiscible
• miscible


  when two liquids are mixed up, they always end up with clear, colorless mixture/ ex. water + ethanol
• immiscible


  when two liquids that differ in density and will not mix together/ ex. water + oil
• water


  a universal solvent
• water


  its molecules have strong positive and negative charges, they can pull apart and get between other molecules or pieces of molecules with charged parts
• types of solution


  unsaturated, saturated, supersaturated
• unsaturated solution


  solution which can be dissolved further amount of solute at a particular temperature
• saturated solution


  solution which can not dissolve further amount of solute at a particular temperature
• supersaturated solution


  it refers to the effect of temperature on saturated solution and it has dissolved more amount of solute than can be dissolved by solvent
