Unit 4 Lab: Ionic Reaction CHEM 1806

Purpose: To observe several ionic reactions and practice net ionic equations

Materials: Student Supplied –distilled water

LabPaq materials: 24 well plate, 96 well plate, pipet (empty), Ionic Reaction bag.

Procedure:

**The 24-well plate will hold the chemical droppers. The 96-well plate is where the reactions will take place.

1. Load the well rows.

1. Place 2 drops of cobalt (II) nitrate solution into seven of the A row wells.

2. Place 2 drops of copper (II) nitrate into seven of the B wells.

3. Place 2 drops of iron (III) nitrate into seven of the C wells.

4. Place 2 drops of barium nitrate into seven of the D wells.

5. Place 2 drops of nickel (II) nitrate into seven of the E wells.

2. Load the well columns

6. Place 2 drops of sodium phosphate solution into five vertical wells under column number 1.

7. Place 2 drops of sodium iodide solution into five vertical wells under 2.

8. Place 2 drops of sodium sulfate solution into five vertical wells under 3.

9. Place 2 drops of sodium chloride solution into five vertical wells under 4.

10. Place 2 drops of sodium bicarbonate solution into five vertical wells under 5.

11. Place 2 drops of sodium carbonate solution into five vertical wells under 6.

12. Place 2 drops of sodium hydroxide solution into five vertical wells under 7.

3. Record all observations. If the solution is anything but transparent, a solid has been formed. Milky = precipitate.

Results and Discussion:

Insert a picture of your well plate with the reaction mixtures. (5 pts)

Based on your observations, choose 10 wells that created a precipitate and write the net ionic equations. (8 pts)

When you are finished, save the file as LASTNAME_Ionic and upload it to the Dropbox for Unit 4 Labs.
