What is a pH indicators?
A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.
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.
How does colour changing bubble bath work?
The bubble bath has a dye added to it called Bromocresol Green which is a pH indicator, it will change colour as you change the pH of the bathwater - how acid or alkali the solution is. (Interestingly the one colour it never goes is green!)So as you dilute the bubble bath, which starts off slightly acid, the pH then gets higher and the water becomes more alkaline, making the Bromocresol Green change from orange to blue. If the water becomes acid again it will change from blue back to orange.
