Complete the following lab.Observations: Quantitative, Qualitative, Physical Change, and Chemical Change

Part 1Add 100 mL of water to a 250-mL beaker. Add three drops of food coloring to the beaker of water.Record observations.

Part 2

Using a spot plate, fill of a well with ammonia.Add 1 drop of phenolphthalein.Make observations.Add vinegar to the top of the well.Record observations.

Part 31. Using a lab scoop, place one scoop of Copper II Sulfate also named Cupric Sulfate in a mortar.

2. Use a pestle to grind the Copper II Sulfate into a uniform powder.

3. Place the powder in a crucible.

4. Set up a ring stand with Bunsen burner as shown.

5. Heat gently with the Bunsen burner for four minutes or until the Copper II Sulfate turns white.

6. Pick up crucible with tongs and place on a square tile to cool for five minutes. (You can work on a different part of this lab while it cools.

7. Use a wash bottle, to add some water to the crucible.

Part 4DO THIS EXPERIMENT IN THE FUME HOOD.

1. Note the appearance of magnesium ribbon.2. Place a watch glass in the fume hood. 3. Light the Bunsen burner in the fume hood. Using tongs, hold the magnesium ribbon in the hottest part of the flame. DO NOT LOOK DIRECTLY AT THE BURNING MAGNESIUM.4. Let the burnt magnesium ribbon fall onto a watch glass.5. Record observations.

Part 5Fill a 250 mL beaker with water.Place a table of Alka-Seltzer in the water.Make and record observations

Part 6Add one level teaspoon of corn starch in a 250 mL beaker.Add 2 mL of water and stir.Keep stirring.Pour the solution into your hand.Record observations.
