solution to --------------------.

to -------------- in basic solution
​

Answer 1

Explanation:

i) China rose converts acidic solution to dark pink, basic solutions to green colour and has no colour change for neutral solutions.

ii) 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.
