Real Lab Procedure:
Take 25 ml of coconut oil in a measuring cylinder and pour it into a 250 ml glass beaker.
Measure 30 ml of 20% NaOH solution in another measuring cylinder and add it into the beaker containing vegetable oil.
Vigorously stir the mixture using a glass rod.
Touch the beaker from outside. It is observed that the beaker is warm.
Place the beaker on a wire gauze placed over a tripod stand.
Heat the beaker using a Bunsen burner till the mixture become a whitish paste.
Remove the beaker from the flame and allow it to cool.
Dip a red litmus paper in the suspension formed.
When dipped in the suspension, the red litmus paper changes its colour to blue.
Dip a blue litmus paper in the suspension.
The colour of blue litmus paper remains the same.
To the above suspension, add 15g of common salt and stir it well with a glass rod.
After adding common salt, soap in the suspension gets precipitated out as solid.
Take a filter funnel and place a filter paper in it and fix it in a stand.
Place a beaker below the funnel.
Pour the contents of the beaker into the funnel over a glass rod and filter the contents of the beaker.
After filtration, soap is left behind in the filter paper.
Transfer the soap into another filter paper using a spatula and dry it by pressing with another filter paper.
Then, cut it into desired shape with a knife.
