Question

After exploring the lab materials, including the Color Key, which statement below is

correct?
(A solution that turns yellow means that there are high levels of carbon dioxide
present
Blue means that there is medium levels of carbon dioxide in a solution,
A green solution indicates no carbon dioxide.

Answer 1

I’m pretty sure the answer is A because carbon dioxide causes a solution to turn yellow and a solution that indicates no carbon dioxide would be blue instead of green.
