The colour of phenolphthalein indicator in dilute HNO isA. colourlessB. orangeC. pinkD. purple

Take about 2 mL of dilute NaOH solution in a test tube and addtwo drops of phenolphthalein solution.n What is the colour of the solution?n Add dilute HCl solution to the above solution drop by drop.n Is there any colour change for the reaction mixture?n Why did the colour of phenolphthalein change after the additionof an acid?n Now add a few drops of NaOH to the above mixture.n Does the pink colour of phenolphthalein reappear?n Why do you think this has happened?

In the titration experiment you carried out in your CHM 108 practical, the colour change of yoursolution when using the phenolphthalein indicator isA. Colourless to PinkB. Pink to ColourlessC. Pink to RedD. Pink to Yellow

Sodium hydroxide turns phenolphthalein solution -Deselect Answer Pink Yellow Colourless Orange
