    Redox Problems:
    I will Assign 1/3 of these problems. Make sure you you do a net ionic Equation for the second half of the handout. Also, If the problem has hydroxide, ammonia or ammonium in the reactants or products then it is basic. Conversely, If the problem has an acid in it then it is Acidic. Evaluate each problem for these clues. If there is neither an acid or base then assume it is acidic. Put your signs on your final answer. Check for balanced mass (number of atoms) and balanced charge.

    When you have two compounds added to each other with the same anion, there will be a complex ion produced.

    in water. Organic compounds with a metallic ion follow the solubility rules.
    When you have an organic compound like "hexane", the "hex" tells you the number of carbon atoms and the number of Hydrogen atoms is twice that number plus 2. CnHn+2 Common "ane" are methane has one carbon, ethane has 2 carbons, propane has 3 carbons, butane has 4 carbons, and the rest use the prefix to denote number like noted in the first part of this note.
    When you have an organic compound, most have a prefix that denotes number except methane, ethane, and propane which have one, two and three carbon atoms respectively.

    When you have an organic compound that ends in "ol" like ethanol, the ethane has two carbon atoms and one of the usual hydrogen atoms will be replaced with and "OH" ion. These are alcohols and always have an "OH" ion. So the formula in the bullet above is the same except one of the hydrogen atoms will be replaced with the hydroxide.
    Sulfur in its standard State is S8.
    Phosphorus in its standard state is P4.

    this test. SHOW YOUR WORK!!!
    Notes:
    When the problem asks about forming ions 2 units lower in charge than expected from the group number, this refers to the “inert-pair effect”. This effect occurs in heavy metals of the “p” sublevel in the first 3 electron positions.
