Procedures
Part A: Reactions Of Iron(III) Chloride, FeCL3
Add a sm tout ensemble sum of money of Iron(III) Chloride crystals(also called ferric Chloride) to 3 exam tubes. The amount of crystals in individually screen out tube should be no longer than the head of a wooden match.
Add a similar amount of Potassium Thiocynate crystals to a 4th test tube and a similar amount of Potassium Hexacyanoferrate(II) crystals to a 5th test tube.
To each of the 5 test tubes, summarize distilled water to a 3-ml mark. Stir each of the systems by thrum with your fingers on the loosely held test tube.
To a 6th test tube, add about 1-ml Silver Nitrate solution.
Label each test tube with the name of the chemical you used.
Record these observations:
trunk 1: FeCL3 dodging 2: KSCN
System 3: K4Fe(CN)6System 4: AgNO3
7. Mix pairs of solutions in the following ways, and record all of your observations in the data table.
System 5: FeCL3 + KSCNSystem 6: Fe CL3 + AgNO3
System 7: FeCL3 + K4Fe(CN)6
Part B: Reactions of Acids
To quartet of your calibrated test tubes, add 3-ml of hydrochloric vinegarish, and to four different test tubes add 3-ml of HNO3.รข€¦Test the reaction of the acids to litmus paper by dipping a glass rod into the test tube containing the acid you are testing and touching it gently to both the profane and red litmus paper. Record observations in the data table. present sure you rinse off the glass rod surrounded by acids.
Gather a small, pea-size sample of each of the following metals: Al, Zn,...If you call for to get a full essay, order it on our website: Orderessay
