Question

. 10 drops of dilute hydrochloric acid is mixed with 2 drops of
phenolphthalein solution followed by sufficient adding of baking soda.
What would be the result ?
​

Answer 1

Answer:

It will become pink in colour.

Explanation:

As 10 drops of dilute HCL is mixed with 2 drops of phenolphthalein solution, the colour of the solution will become colourless because When phenolphthalein indicator is added to an acidic solution it becomes colourless and when it is added to a base it turns into pink colour. So after adding baking soda it the solution would become pink because NAHCO3 (Baking Soda) is basic in nature. If you want you can marks me as brainliest.
