Solubility Of Salt And Potassium Chloride Lab Report

When placing the large test tube in boiling water, be sure to keep the face of the large test tube away from you or any lab partners with safety tongs.

2. Used a test tube clamp to held the test tube and gently heated the tube in a laboratory burner flame for about 30 seconds.

Step 2: Place a saucepan with tap water on a burner and bring to a boil.

21) After all of the solid dissolves, move the flask from the hot plate and allow it cool to room temperature. After a while, crystals should appear in the flask.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.

Fill a test tube about 1/3 full with cold tap water for use in step 34.

Next prepare the third test tube with an accurate measurement of 5ml sodium carbonate once again labelling appropriately.

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

Tube 4 now should only have crude solid in the tube and it is then weighed. The tube is placed into a 50℃ water bath and then approximately 0.5 -1 ml of methanol is added, as well as H2O until the solution gets cloudy, once the solution is dissolved it is cooled to room temperature and then iced. The crystals are then collected using a Hirsh funnel. Next a small amount (~ 0.1g) of the crystals are placed into a melting point tube and placed into the melting point machine to record the unknown neutral substances melting point.

1 ml of water should be added to the first test tube and make a note. In the second test tube, 1 ml of methyl alcohol should be added. In the third test tube, 1 ml of hexane must be added. Lastly, the fourth test tube will be a control.

Label the 3 test tubes with your initials and number each 1,2, and 3. (This allows for them to be distinguished)

Add 2 drops of soap to the removed test tube, and place it in the test tube holder.

1. Number four clean test tubes 1-4. 2. Place 1 ml (or 20 drops) of the following solutions into each tube: water, egg albumin, starch, and chicken broth. 3. Add 3 drops of Buiret reagent to each tube and gently shake

7.When water bath is ready, put each test tube into the water bath. Wait 5 minutes.
