What we did in class:

-Went over Double Replacement Reactions and Solubility Lab

-Were scared by a dog and a character from Star Wars

    • Correct Way to write a molecular reaction 
    •  Fe(NO3)3 (aq) + NaOH (aq) --> NaNO3 (aq) + Fe(OH)3 (s)                            
                                                                           soluble!

3.Sulfate anion Chloride anion Iodide anion   
               -Chloride and Iodine are both Halides

   React with all EXCEPT with silver

4. Carbonate, Hydroxides, Phosphates

Alkali metals tend to be very soluble

5. Soluble because it is a Halide and is expected to act like other halides, which tend to be very soluble.

                       GENERAL RULES OF SOLUBILITY

HW: #1-5 on Solubility of Common Compounds worksheet (handed out on Monday). Due tomorrow.

        Web-assign due Sunday night 11:59 P.M.
