Question

a drop of phenophthalein is added to lime water. what do you observe?​

Answer 1

Answer:

$\huge\star\blue{answer}$

Lime water is a base, so when the phenolphthalein was added to the solution, it turned the solution pink. When I exhaled into the solution, the carbon dioxide in a person's breath reacted with the water to form Carbonic Acid. ... Therefore with the phenolphthalein, the color disappears in the now acidic solution.

Answer 2

Answer:

If 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.
