PURPOSE: To see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. PROCEDURE:
1 Cotton Swabs, 1 Sheet each of white and black paper, 1 Distilled water, Goggles-Safety, 1 Well-Plate-24,1 Well-Plate-96, Bag-CK1 1 Pipet, Empty Short Stem, Experiment Bag Ionic Reactions 1 Barium Nitrate, 0.1 M - 2 mL in Pipet, 1 Cobalt (II) Nitrate, 0.1 M - 2 mL in Pipet1 Copper (II) Nitrate, 0.1 M - 2 mL in Pipet, 1 Iron (III) Nitrate, 0.1 M - 2.5 mL in Pipet, 1 Nickel (II) Nitrate, 0.1 M - 2 mL in Pipet, 1 Sodium Bicarbonate, 0.1 M - 2 mL in, Pipet, 1 Sodium Carbonate, 0.1 M - 2 mL in Pipet, 1 Sodium Chloride, 0.1 M - 2.5 mL in Pipet, 1 Sodium Hydroxide, 0.1 M - 2 mL in Pipet, 1 Sodium Iodide, 0.1 M - 2.5 mL in Pipet, 1 Sodium Phosphate, 0.1 M - 2 mL in Pipet,1 Sodium Sulfate, 0.1 M - 2.5 mL in Pipet CAUTION! Sodium hydroxide is caustic and can burn skin and clothes if it touches them. Rinse any spills well with copious amounts of water. Also, most of these chemicals are toxic by ingestion. So remember, no food or drinks in the lab!

1. All reactions will be performed in the 96-well plate.
a. Place 2 drops of cobalt (II) nitrate solution into seven of the A row wells. b. Place 2 drops of copper (II) nitrate into seven of the B wells. c. Place 2 drops of iron (III) nitrate into seven of the C wells. d. Place 2 drops of barium nitrate into seven of the D wells. e. Place 2 drops of nickel (II) nitrate into seven of the E wells. 2. When performing the following, NEVER TOUCH THE TIP OF THE PIPET TO THE SOLUTION ALREADY IN THE WELL!

a. Place 2 drops of sodium phosphate solution into five vertical wells under column number 1.
b. Place 2 drops of sodium iodide solution into five vertical wells under 2. c. Place 2 drops of sodium sulfate solution into five vertical wells under 3. d. Place 2 drops of sodium chloride solution into five vertical wells under 4. e. Place 2 drops of sodium...
