Question

Does SO2 also make Ca(OH)2 milk white in colour, like CO2?

Answer 1

To be honest about it I've never seen this done but I think the answer is yes. CaSO3 and CaCO3 in a fine suspension probably look alike. BTW, if I see it I usually don't answer questions posted using different screen names but I'll take a look at your other post by Thomas anyway.

Answer 2

Thank you!

And my brother uses the screen name Thomas and we access the site through the same device.
