Today I want to tell everyone that I made a science test, the test is to mix limewater and CO2, inside desiccant, there are some limestone, and limestone can make limewater.
We blow the air we breathe out, because in the air we breathe out, there are 4 % CO2, so we use a straw to blow the air in.
When the limewater and CO2 mix, the original limewater ( Ca(OH)2 ) will mix with CO2, so it will become CaCO3, and the limewater will be muddy.
This is our science test, and if you have a bag of dried seaweed, there are desiccant, so you can use it to complete this test.
I think this test is useful, because it let me understand a lot about limewater and lime, I wish I can find more materials to make tests.
