Question

what do you observe when few drops of sodium hydroxide(NaOH) solution is added to three test tubes

containing red litmus, distill water and phenolphthalein.​

Answer 1

When sodium hydroxide solution will be added to the test tube containing red litmus it will turn it to blue.

When sodium hydroxide solution will be added to test tube containing distilled water then there will be no change.

When sodium hydroxide solution will be added to the test tube containing phenolphthalein it will turn the solution pink because Sodium Hydroxide is a base which turns phenolphthalein to pink colour
