Question

sulfuric. acid effect on litmus paper and turmeric paper​

Answer 1

Answer:

If we put a drop of an acid on this turmeric paper (which has been turned red by a base), then the turmeric paper will change from red to yellow. This is because acid cancels the effect of base and restores the original yellow colour of turmeric paper.

Explanation:

Colour of litmus paper in acid: Blue litmus paper turns into red when dipped in acidic solution. Colour of litmus paper in base: Red litmus paper turns into blue when dipped in basic solution. ... Turmeric paper turns into red when it is dipped into basic solution. Turmeric paper does not change its colour with acid.
