Solubility experiment Flashcards
What is the aim of the solubility experiment?
To measure the solubility of a salt at different temperatures.
What equipment do you need to prepare for heating and cooling?
A hot water bath and an ice bath.
How much distilled water is measured initially, and where is it placed?
4 cm³ of distilled water is measured into a boiling tube.
How much ammonium chloride is weighed out?
2.6 g of ammonium chloride.
What do you do after adding ammonium chloride to the boiling tube?
Place the boiling tube in the hot water bath and stir until the solid dissolves.
What happens after the ammonium chloride dissolves?
Transfer the boiling tube to the ice bath and stir until crystals first appear.
What should you note during the cooling process?
The temperature at which crystals first appear.
What do you do after noting the temperature in the first cycle?
Add 1 cm³ of distilled water, warm the solution to dissolve crystals, then repeat the cooling process.
How long should you repeat the steps?
Until a total of 10 cm³ of water has been added.
