1. Question⇒  Three unlabled test tubes containing pure water limewater,and lemon juice were later marked A,Band c respectively ,A drop of chemical X was ,added in each of these test tubes. The colours of drop of liquid X in A,Band C changed to yellow,red and orange, respectively identify the _ 1_ A) chemical X 2_) liquid in test tubes A,BandC respectively​?

Explanation:

• In test tube A containing Distilled water , the length of foam will be longer  .
• In test tube B --- Under ground water --smaller length of foam
• In test tube C-distilled water + Pinch of CaSO4 --- minimum
• length of foam as the soap solution is wasted in reacting with
• calcium ions present in test tube c to form insoluble precipitate called scum
