Turmeric Indicator Papers

Product Description

• When dipped in a basic solution, turmeric paper turns red or deep red. When dipped in an acidic solution, the paper remains yellow. 

• Turmeric paper can indicate the presence of alkalis, which turn it brown, or of boric acid, which turns it reddish-brown. 

• To make turmeric paper, you can:
  1. Extract the color from turmeric powder by adding it to water or alcohol. 
  2. Apply the extract to absorbent paper, such as blotting paper or a kitchen towel. 
  3. Dip the paper strips into the solution, making sure the entire strip is coated. 
  4. Remove the strip from the solution and let it dry completely.
