An ebullioscope is an instrument for measuring the boiling point of a liquid.
How do you measure boiling point?
- put a boiling stone in the mini test tube.
- add about 1/2 inch of liquid.
- clamp in stand in the fume hood.
- insert thermometer into test tube with bottom of mercury bulb about 1/2 – 1 inch above the liquid.
- carefully heat with mini bunsen burner till temperature remains constant.
- read temperature.
What tool is used to measure melting and boiling point?
A melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus.
Which equipment is used to measure the boiling point of a liquid?
A laboratory thermometer should be used to measure the boiling point of a liquid because it has a greater range.
Which thermometer is used to measure the boiling point of a liquid and why?
A Celsius thermometer will measure the boiling point of water at 100° and its freezing point at 0°; a Fahrenheit thermometer will measure the same events at 212° for the boiling point of water and 32° as its freezing point.
What technique is used to measure the boiling point of solids or high boiling point liquids?
The distillation method of boiling point determination measures the temperature of the vapors above the liquid. Since these vapors are in equilibrium with the boiling liquid, they are the same temperature as the boiling liquid.
What is a Thiele tube used for?
Beckmann’s thermometer is used to determine the boiling point elevation (or) freezing point depression.
