Solution:
The above statement is true.The combination of solutions like solution, and sugar solution can be distinguished by use of phenolphthalein. To all the liquids, first, add phenolphthalein separately. Among all the solutions, one will surely turn pink in colour i.e sodium hydroxide(). Then, add a few drops of other solution to the sodium hydroxide solution. The solution will be hydrochloric acid() if it again converts the sodium hydroxide solution colourless, and the remaining solution is a sugar solution.
Reaction:
