1 PREPARATION FOR CHEMISTRY LAB SOLUTIONS. A change in the color of the acid-base indicator phenolphthalein, clear in its acidic form and pink in its basic form, added to the analyte solution, will determine the endpoint of the titration. if the indicator has been chosen well, the endpoint will coincide with the equivalence point of, phenolphthalein is a colourless, weak acid which dissociates in water forming pink anions. under acidic conditions, the equilibrium is to the left,and the concentration of the anions is too low for the pink colour to be observed..

Phenolphthalein in a 1% alcoholic solution is also used as a visual indicator in titrations of mineral and organic acids and most alkalis. phenolphthalein-titrated 1 phenolphthalein-naoh kinetics phenolphthalein is one of the most common acid-base indicators used to determine the end point in acid-base titrations.

Methyl orange is a ph indicator frequently used in titrations because of its clear and distinct colour change. because it changes because it changes colour at the ph of a midstrength acid, it is usually used in titrations for acids. preparation of 0.1 mol/dm3 hcl titrant and determination of its exact concentration a.) preparation of the solution: add approx. 1.0 g of mannite and 2 drops of phenolphthalein indicator to each sample. after adding mannite to the solution, it turns red first (acidic color of methyl orange), then, during the titration, it turns yellow (basic color of methyl orange). continue the titration
