Answer 2

Vinegar

When turmeric powder is added to lime, the resulting solution becomes basic which turns the solution red.

In order to turn the solution back to its original yellow color, an acid must be added to the solution (which is vinegar in this case). The acidic vinegar and basic turmeric solution react in a process called the neutralization reaction and yield the resultant yellow color.

NOTE: If you are trying this at home, take maximum precaution as acid-base reactions are violent and potentially dangerous.
