Concentration

(Lecture id-1220)

TOPICS & OBJECTIVES

1010 - Concentration
    1080 - Know the definitions of solution, solvent, solute and concentration.
    1090 - Understand molarity, molality and mole fraction are measures of concentration.
    1105 - Calculate the molarity of a solution prepared by dissolving a mass of solute in a volume of solvent.
    1110 - Convert between moles solute, molarity solution and volume of a solution.
    1130 - Determine the molarity of a diluted solution from initial molarity and volume added.
 
1020 - Solution Stoichiometry
    1090 - Convert the volume of a solution to moles of reactant, using molarity.
    1095 - Use stoichiometry to determine moles of a product produced from volume of a reactant solution.
    1150 - After finding moles of a product produced, determine the molarity of the product in solution.
    1250 - Use titration as a method to determine the concentration of an unknown solution.
 
1030 - Electrolytes
    1005 - Be able to identify and distinguish between molecular and ionic compounds.
    1010 - Know ionic substances dissociate when dissolved in solution.
    1020 - Distinguish between ionic (electrolytic) and molecular solutions.
    1030 - Distinguish between ionic substances that strongly dissociate and weakly dissociate.
    1040 - Know acetic acid and hydrofluoric acid are weak electrolytes.
    1050 - Know ionic compounds that do not dissolve in solution and molecular compounds are non-electrolytes.
    1060 - Know the electrolytic strength of a solution is directly proportional to electro-conductivity.
