When you said the water was "impure" in your previous comment, no one thought you meant it was sullied with... air. While not technically incorrect, if you honestly thought "impure" was a good way to describe water with air dissolved in it, the best I can say is to watch out for your subtext when using a word much differently than basically anyone else does. |

> Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. [1]
Other sources list carbon dioxide, oxygen, and nitrogen as impurities that can cause corrosion in pipes [2], or can form bubbles in systems where there are major changes in pressure or temperature, blocking pumps, fine tubing, filters, etc. [3]
So it’s a bit context dependent, but there are situations where it is totally reasonable to view dissolved gases in water as an impurity. And this context - the discussion of what makes ice clear or cloudy - is one of them.
How can you claim so confidently that “no one thought” something, or that the parent is “using a word much differently than basically anyone else”? If you honestly think that you speak for all 1.35 billion English speakers in the world - or even all the people reading this thread - the best I can say is speak for yourself.
