Question

what happens when excess of hcl is added to test tube containing sodium hydroxide and few drops of phenolphthalein

Answer 1

Answer:

It may burst if conc this may happen becuse of the chemucal reaction so i say u must never try that if u want to live further

Answer 2

Answer:

U know that phenolphthalein is an indicator which indicates the presence of a base in a solution. And we very well know that NaOH is a base , so firstly the solution would be of pink colour. But it is also a fact that phenolphthalein doesn't show any change of color when mixed with an acid, and also HCl is an acid. So, when this HCl is added in the solution at a high rate , the pink colour of the initial soln will turn white.

Hope it help..
