Purpose
This lab experiment will provide the experimenter with an opportunity to understand the nature of ionic reactions. This experiment will show how these reactions occur by giving examples of reactions, such as precipitation reactions, and breaking down these reactions by use of equations to see the net ionic reaction. This lab provides the unique opportunity to not only predict ionic reactions, but also see them through experimentation. A better understanding of balanced equations, solubility rules, aqueous solutions, and ionic reactions in general will most likely be better understood upon completion of this experiment (LabPaq CK-1).
Procedure
- I first read through entire procedure and then set up lab area.
- I obtained a light and dark sheet of paper to view reactions against both a light and dark background.
- Set up a 96 well plate and arranged all chemicals needed to perform experiment. I then constructed a table to record all observations and possible precipitates viewed.
- I placed two drops of cobalt (II) nitrate into 7 wells under row A in the well plate. (Two drops in each of the seven wells)
- I then followed the same procedure as with the cobalt (II) nitrate with 4 more substances in 4 different rows. 2 drops copper (II) nitrate in seven wells of row B, iron (III) nitrate in row C, barium nitrate in row D, and nickel (II) nitrate in E.
- I then put two drops of sodium phosphate solution into five vertical wells under column one.
- I then followed the same procedure as with the sodium phosphate solution with 6 more substances put into 5 different vertical wells.
- 2 drops sodium iodine into 5 vertical wells under 2, 2 drops sodium sulphate solution in 3, sodium chloride solution in 4, sodium bicarbonate solution in 5, sodium carbonate solution in 6, and sodium hydroxide solution in 7.
- After recording all reactions, I cleaned up and thou rally cleaned the well plate as well as disposed of anything no longer needed.
