LAB WORKSHEET-1
MELTING POINT OF ICE AND BOILING POINT OF WATER
 
Objective: To study the boiling point of water and ,melting point of ice and influence of impurity on MP and BP of substances.
 
Requirements:
 
Distilled water, common salt or sugar, ice , Lab thermometer, 250 ml & 100 ml beakers, glass rod, etc

Procedure:
 
 
Step – 1
 
1. Take 25 ml of distilled water in a clean beaker (100 ml).
 
2. Insert a thermometer in such a way that its mercury bulb is fully immersed in the water taken. ( Use an iron stand to hold the thermometer )
 
3. Now heat the beaker containing water on a Bunsen flame. ( Use tripod stand & wire gauze)
 
4. Wait till the water boils. Note the temperature and record in the table given below.
 
Step – 2
 
1. Take 25 ml of distilled water in a 100 ml beaker. Add half a spatula of common salt to it and stir well to dissolve.
 
2. Find the boiling point of as explained in step – 1. Record the temperature.
 
Step – 3
 
1. Take some crushed ice or ice gratings made with distilled water, in a 100 ml beaker.
 
2. Insert a thermometer into the crushed ice.
 
3. Wait till the thermometer shows a steady reading. Record the temperature in the table given below.
 
4. Repeat the experiment with ice made with salt water. Record the temperature.
