When phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
What would you mix an alkali or acid with to get a coloured substaince?
You could mix an acid or alkali with an indicator such as methyl orange or phenolphthalein. Phenolphthalein is colorless in an acidic medium and pink in an alkaline one.
Which colour does a strong alkali turn litmus paper?
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.
