C125 Experiment #4 Chemical Reactions – Report Sheet P age 1/9 Name(s)________________________        TA Initial _____________________   One lab report per student pair  is due at the end of your lab period on 2/23 or 2/25. You do not need  to prepare pre-lab notebook pages for this lab, but you must record all your observations on your  report sheet. WRITE NEATLY!  BE CONCISE, YET COMPLETE. Important to review when you write your total and net ionic equations: ONLY  the following materials can be broken down into ions: 1. Soluble ionic salts, such as NaCl, CuSO 4 ; 2. Strong bases, such as NaOH, Ba(OH) 2 ; 3. Strong acids, such as H 2 SO 4 , HCl. Materials that  CANNOT  be broken down into ions: 1. Anything having a non-aqueous state-of-matter, such as solids (or precipitates), gases, liquids (or  solvents). Examples: AgCl(s), CO 2 (g), H 2 O(l) 2. Weak acids and weak bases, such as HF(aq), NH 3 (aq) 3. Non-electrolyte, such as ethanol in water, or CH 3 CH 2 OH(aq).  I. Reaction series #1 Observation #1A Observations of ~ - Chlorine in  water: - Chlorine in methylene chloride (the organic layer): - Bromine in water: - Bromine in methylene chloride (the organic layer):
