Turmeric is a natural indicator. On adding its paste to acid and base separately, which colours would be observed
(a) Yellow in both acid and base.
(b) Yellow in acid and red in base.
(c) Pink in acid and yellow in base.
(d) Red in acid and blue in base.
Turmeric paste is yellow in colour and it is acidic in nature hence it shows yellow color in acid whereas it is converted to red due to neutralization by the base.
Hence option (B) is correct.
