This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases. Learners can use their indicator to test household chemicals and determine which are basic. This activity requires adult supervision since it uses isopropyl alcohol, also known as rubbing alcohol. This activity (located on page 2 of the PDF) is one of three activities in the Take Home guide for the Everyday Chemistry unit in OMSI's Chemistry Lab. Included in the PDF are two additional activities: Iron in Cereal and Mystery Writing.
