1.	(c)You have four solutions A, B, C and D. The pH of solution A is 6, B is 9, C is 12 and D is 7.State the change in colour of pH paper on dipping in solution C and D.
Answer» Answer: The COLOUR of the pH paper on dipping in SOLUTION C will change to INDIGO ( purple), because it is basic in NATURE with pH value = 12. The colour of the pH paper on dipping in solution D will change to medium green, because it is neutral in nature with pH value = 7. Explanation: The more acidic the pH colour will be extending yellow to red. The more basic the pH colour will be extending BLUE to deep violet.
