Dio the turmeric indicator in all the solution ,the solution which turn it red is a base i.e. sodium hydroxide. Now take the other two solution and pour them slowly one by one in the sodium hydroxide solution dipped with turmeric indicator . When one of the solution is poured in sodium hydroxide the red colour of turmeric slowly changes back to yellow because neutralisation reaction occurs, the solution is hydroxide acid. This way the solution left is sugar solution .
