Two solutions A and B 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 phenolphthalein from colourless to pink?

Solution A is having a pH of 3.0 so it will be acidic as it is lesser than 7. Thus it will change the litmus solution from blue to red and the solution B is basic as it is having a value of pH 9.5 it will turn phenolphthalein from colourless to pink.
