Write the steps you would use for making tea. Use the words solution, solvent, solute, dissolve, soluble, insoluble, filtrate, and residue.
Answers
(a) Into a vessel, add a cup of milk which is the solvent, supply it with heat.
(b) Add tea powder or tea leaves to the boiling milk, which acts as a solute. Continue to heat
(c) The solute i.e., the tea powder remains insoluble in the milk which can be observed while it is still boiling.
(d) At this stage, add some sugar to the boiling solution while stirring
(e) Sugar is a solute but is soluble in the solvent
(f) Continuous stirring causes the sugar to completely dissolve in the tea solution hence reaching saturation.
(g) Once the raw smell of tea leaves is vanished and tea solution is boiled enough, take the solution off the heat, filter or strain it to separate tea powder and the tea solution. The insoluble tea powder remains as a residue while the solute (sugar) and the solvent (essenced milk solution) strain through the filter medium which is collected as the filtrate.
Answer:-
Steps involved in tea making:
(i) Take 100ml of water as a solvent and boil it a few minutes.
(ii) Now add one teaspoon sugar, one teaspoon tea leaves and 50ml of milk. Here sugar, tea leaves and milk are solutes.
(iii) Now boil it again for a few minutes so that sugar will dissolves in solution as sugar is soluble in water.
(iv) Now filter the solution. Collect the filtrate in a cup. The insoluble tea leaves will be left behind as residue.
