Three liquids are given to you. One is hydrochloric acid, another is sodium hydroxide and third is a sugar solution. How will you identify them? You have only turmeric indicator. *
Answers
Explanation:
Turmeric indicator turns red in a basic solution whereas remains yellow in acidic and neutral solution. ... One is hydrochloric acid which is acidic another is sodium hydroxide which is base thus, the solution is basic and lastly we have a sugar solution which will be neutral.
Answer:
Turmeric will turn pinky-red in alkali, but is yellowish in both acid and neutral solutions.
So test some of your three solutions with turmeric, and the one that turns the indicator pink is the sodium hydroxide solution.
Now that you know which is NaOH, mix some of thi, separately with some of the other two solutions. The one that gets warmer is the HCl - the neutralisation of HCl with NaOH is exothermic. There is no (rapid) reaction of sugar solution with NaOH so it shouldn't change temperature by much.
