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.

Simulator Procedure:
