Perform an extraction on 1/4 teaspoon of ground turmeric using 1/4 cup rubbing alcohol.
Filter the mixture through a coffee filter, fitted to a sieve. save the effluent.
use as effluent, or saturate thin paper strips and use like litmus paper.
Turmeric will indicate an acid, by turning yellow.
It will indicate a base by turning red.

What substance is used to determine the presence of an acid or base?
by using an indicator like litmus paper!!!
What is the best way to determine whether a substance is an acid or base?
A pH meter gives a direct reading which is great when testing wine or soft drinks. Litmus paper will go red in acid or blue in base. An acid will liberate carbon dioxide from chalk - a base will not You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic. Turmeric indicates acid by turning strong yellow. Base is indicated by red. Phenolphthalein indicates bases by turning red or purple. Acid is indicated by no color.
