  1. Unit Five Solubility Equilibrium

  2. Review ___________________ a substance which dissolves to yield a solution with ions that can conduct electricity Eg. (NH4)3PO4(s)  3NH4+(aq) + PO43-(aq) HCl4(g)  C2H2(g) 

  3. An_______solution contains ions. An ______________solution contains only neutral molecules.

  4. How do you know if a compound will form an ionic or molecular solution? These are some guidelines, but there are exceptions:  _______ compounds consisting of a metal and a non-metal are likely to form ionic solutions Eg. FeCl3(s) Fe3+(aq) + 3Cl(aq) • A compound with ___________________ ions will likely from an ionic solution Eg. (NH4)2Cr2O7(s) 2NH4+(aq) + Cr2O72(aq)

  5. NOTE: In Chem. 30, we will only be working with compounds with 1+ and 1- ions. Eg. NaH3P2O7(s) Na+(aq) + H3P2O7(aq)  _______________ compounds (AKAcovalentcompounds) made of 2 or more non-metals, especially_________________compounds are likely to be a molecular solution Eg. ClO2(l) ClO2(aq) Eg. CH3OH(l) CH3OH(aq) (organic b/c it starts with C)

  6. In Chemistry 20… The _______________________ of a substance is the maximum amount of the substance which can dissolve in a given amount of solvent @ a giventemp. A solution which has dissolved the “max. amount” of a substance is said to be ____________________. Once a solution has been saturated the addition of more substance will cause it to sink/float undissolved in the solution.

  7. In Chemistry 30… The _____________________ of a substance is the __________________ concentration of the substance @ a given ______________ The solubility is referred to as the ____________ solubility where the [] is expressed as “moles/litre” A substance is said to form a saturated solution if the dissolved substance is in _____________with some of the __________________ substance.

  8. Saturation exists when: some undissolved material is present equil. Exists b/t the dissolved and the undissolved material Eg. AgBrO3(s) Ag+(aq) + BrO3(aq) Dissolving equation

  9. A Closer Look In the beginning… AgBrO3(s) Ag+(aq) + BrO3(aq) = dissolving rxn. Then… Ag+(aq) + BrO3(aq) AgBrO3(s) = ________________ rxn. Eventually… AgBrO3(s) Ag+(aq) + BrO3(aq)

  10. Assignment  “Solubility Equilibrium I” handout; Q 1 – 7.
