A pure substance is a substance that cannot be separated by physical means. To determine whether a substance is pure, let a container of it evaporate. If there is no residue then the substance is pure.
the colour of water is actually clear but it looks blue but that is the Skys reflection!!!
Blue, Red, and Yellow
Gold will not change the color of water.
no, pure water is absolutely clear. it doesnt have any color whatsoever. if there is a yellowish color, it means there are impurities in the sample.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
If it is pure water, it doesn't change.
water is pure h2o(depending where you get it) dummy your question makes as much sense as a rock moving.

The color is different for each system; if the approx. pure water is the supernatant, this is colorless.
It depends whether the water is pure (Green) or with alkalis in it (Blue)
Pure water is neutral so the color will be green.
Pure water is evaporated faster.
Pure water is pure because it is pure... and because it is pure, it is pure... Got it... What sought of question is that?
