*solutions

• Diff Solutions


  more particles of the solute are dissolved in a concentrated solution than on a dilute solution
• Solubility


  a solid that dissolves or doesn't dissolve in a solvent is soluble, (eg; salt in water) or insoluble (eg; iron fillings in water)

  
  

  some soluble substances have a greater solubility than others such as sodium chloride and lead chloride
• Saturated Solution


  when no more solute will dissolve as the solvent has reached its limit
• Temperature and solubility


  most solutes dissolve more quickly/ easily in hotter water as the particles get more energy, so vibrate and move more.

  as the temperature increases, the solubility of most solutes also increases.
• Other Solvents


  some solutes are dissolvable in other but not in water and vice versa, eg; nail polish doesn't dissolve in water but dissolves in nail polish remover.
