Question

Two solutions X and Y have pH values of 3.0 and 9.5 respectively. Which of these will turn litmus solution from blue to red and which will turn phenolphthalin from colourless to pink?

Answer 1

X will turn blue litmus to red because it is acidic in nature having pH value less than Z. y will turn phenol phthalein from colourless to pink because it is basic in nature having pH value greater than 7.
