Answers
Answer:
When few drops of phenolphthalein are added to a dilute solution hydroxide a pink colour is produced
Phenolphthalein is a weak acid, which is why when it is added in a strong base, it gives pink color and the color gets intense as the PH of the base increases. If a strong acid such as HCL is added in this solution, it with react with base and cause neutralization.
Explanation:
a drop of phenolphthalein is added to lime water ( that is calcium hydroxide ) then the solution will turn colourless to pink colour showing that the lime water is basic in nature.
phenolphthalein is added to water it may turn into pink colour indicating that water contains some impurities but if water is distilled one it will not show any change in colour as it's pH is neutral...
