Question

what will happen if you blow gently in a test tube containing lime water through a straw ?

Answer 1

Pass a straw through the hole into thelime water. Now, blow gently throughthe straw a few times. ... We know thatlime water turns milky when carbon dioxide gas is passed through it. Sincelime water turns milky due to the exhaled air, we conclude that the exhaled air contains carbon dioxide.

Answer 2

hey sister here is your answer

if youcontinue to blow through the limewaterafter the precipitate appears then it will eventually dissolve again. Eventually, the concentrate of Carbonate ions becomes high enough to force the production of Hydrogen Carbonate ions, which are soluble.

hope it helps you
