investigating state changes

Aim: To observe water as it changes state from solid to liquid and then to gas

Equipment:
A Beaker
Thermometer
Busen burner
Heatproof mat
Tripod
Gauze mat
Stopwatch
Retort Stand
Clamp
Ice cubes

Method:
1. Collect enough ice so that you beaker is half full and place the thermometer into it while you set up the rest of the equipment

2. Set up you retort stand and clamp alongside the tripod and gauze mat

3. Place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright and the scale is easy to see.The bottom of your thermometer should be low enough to still be covered by water when the ice melts, but not touching the bottom of the beaker.

4.Record the initial temperature of the ice in a data table.

5. Light the bunsen burner and start timing with a stopwatch.

6.Measure and record the temperature every minute.

7.Continue measuring and recording the temperature until the water has been boiling for 2-3 min

investigating- solubility

Aim- To investigate the solubility of calcium chloride and magnesium oxide to see which is the most soluble.

 Equipment- a 250L beaker, 100 mL measuring cylinder, calcium chloride and magnesium oxide, a stirring rod teaspoon and a ruler.

Method-
1. fill the beaker with 100mL of water
2. add a level of calcium  chloride or magnesium oxide
3. stir  the solution until all of the ingredients have dissolved into the water
4. repeat steps 2 and 3 until the all the calcium chloride.

Saturation

AIM- to make crystals form in a supersaturated solution


EQUIPMENT- copper sulfate powder, 2x250 mL beaker,  a pencil or ice block stick, some cotton string, a stirring rod, hot water (either provided by your teacher or made by heating over a Bunsen burner), a watch glass, a funnel and filter paper.

METHOD-                                    PART 1

  1. pour approximately  150 mL of hot water into a 250 mL beaker.
  2.  add a spoonful of copper sulfate powder and stir until dissolved 
  3. repeat step 2 until no more copper sulfate will dissolve
  4.  filter solution into clean 250 mL beaker 
  5. pour a small amount of this solution into a watch glass 
  6. label your watch glass and beaker and place the watch glass on a window sill

filtration- seperating mixures

aim-to separate a solution from a predicate.

equipment

  • lead nitrate 
  • potassium iodide 
  • conical flask 
  • stirring rod 
  • 250ml beaker 
  • funnel 
  • filter paper 
method:
1. pour Approximately 10 ml of the potassium iodite solution into the beaker
2. add the same volume of the lead || nitrate.
3.your teacher will show you  how to fold the  filter paper so it fits inside your funnel.
4. place the funnel, with the filter paper inside it, into the mouth of a conical flask.
5.stir, then carefully pour the precipitate mixture into the funnel.

observations : when i was watching the chemicals go together it turned into a yellow colour. then when we filtered it (got rid of all the liquid)  stuck to the filter paper was a yellow pastey resadue . when I felt it (i wasn't suppose to but I did) it felt like cornstarch a bit. the cornstarch resadue was rude
