it turns turmeric paper in to red acid or base neutral substance
Answers
Answer:
Base turn turmeric indicator[Natural] to red in colour.
Explanation:
Turmeric is a reddish-yellow rhizome. The more prominent yellow colour is due to the presence of the xanthophyll pigment, while the reddish-orange colour comes from carotene pigment. ... As a result, the yellow xanthophyll is suppressed and the orange-red carotene pigment becomes more prominent, so the turmeric turns red.
Turmeric (and curry powder, which contains turmeric) is an acid base indicator. When it reacts with bases (like baking soda), it changes color to deep red. This red form of the indicator can change back to yellow when acids are added.
If turmeric is added to an acidic solution, it stays its usual yellow colour. Add it to an alkaline solution, however, and it changes colour from yellow to red. Curcumin is again the chemical culprit behind this effect. This time, it's a subtle change in its chemical structure that's responsible.
