1.	Analyse the picture given below.a. Identify ‘A’. b. Write the chemical equation at ‘B’. c. Add few drops of phenolphthalein to the remaining solution after electrolysis. What change will take place? Why?
Answer» a. A – cathode. b. Chemical equation at ‘B’: 2Cl^- → Cl₂ + 2e^- c. Solution turns pink. Because, after electrolysis K⁺ and OH^- ions are present in the remaining solution. That means KOH, an alkali is formed.
