So at 20 degrees C, I think a saturated solution is around 42%. (74.5g per 100ml, that is 74.5g in a total solution of 174.5g.)
My solution, which is labelled as 33%, is now at about 18C, and there is still a very fine sediment. Its should not be a saturated solution, so why is there some sediment? When I shake it, it does have a chalky, cloudy appearance.
