It is a white crystalline powder that turns pink or red in basic solutions and remains colorless in acidic solutions. This property makes it useful for detecting the presence of bases. In simple terms, phenolphthalein is a tool that helps us figure out if a substance is acidic or basic by changing its color. If it turns ... The correct option is- (c) KOH (aq). Phenolphthalein is a synthetic indicator that is used in acid-base titrations. If it is added to an acidic or neutral solution, the solution will turn colourless. The addition of phenolphthalein to a basic solution will turn it pink due to the formation of phenolphthalein ions. As KOH (potassium hydroxide) is a base, the addition of phenolphthalein to its solution will change its colour to pink. On the other hand, all the other solutions are acidic, they ... The colour change observed when the solution of magnesium hydroxide is tested with the following indicators is phenolphthalein turns colourless to pink. What is phenolphthalein ? In an acid-base titration, phenolphthalein is employed as an indicator. It turns pink in alkaline solutions and is colourless in acid solutions as an indicator.
