yes, like places where there aren;t contamination
No, pure ice (frozen water) does not have any sodium in it, because pure ice is just pure water that is frozen, and since water is H2O, and not H2NaO, ice doesn't have sodium in it. Ice will have whatever chemicals or other contaminants in it that were in the water before it was frozen. If the water had salt in it then the ice will be salty too.
Ice from distilled water would be pure. However, everyday ice contains dissolved gasses. For instance, historic greenhouse gas levels can be measured from ice core samples from the Antarctic ice sheet because these gasses were trapped in the layers of ice.
One substance mixing with more of the same substance is not called dissolving, it's just mixing. Ice does not really dissolve in water, it just melts and then becomes part of the water.Added:Ice IS pure water in solid state, the water you mean is pure water in liquid state.When ice (solid) melts it becomes water (liquid)
If made from pure distilled water it is a compound. But usually it is a mixture.
no, then it is gasEDIT: The chemical formula for pure water is always H2O - regardless of whether it's in the form of ice, water or steam ! Snakester1962 (Supervisor)
there is a phase change that is water(liquid) is converted into ice now the question arrives that it is a pure substance or not? if its chemical composition is the same during the phase change then it is a pure substance otherwise not.
Ice is solid H2O so it is a pure substance, at least ideally.
water is pure so is homogeneous ice is pure so is homogeneous oil is pure so is homogeneous
Yes, assuming we are talking about pure water and pure ice. Ice is the solid state of water and occurs at 32 degF or 0 degC.
If ice is made of pure water, then it is a pure substance with a definite composition, H2O, and not a mixture.
Ice water is a compound.
some ice creams are made of natural compound but some are not

Pure water has a natural Ph due to the rate of dissociation to H+ and OH- is equal to rate of association to form H2O. Pure water has no free ions.
When ice forms in a salty body of water such as the ocean, the salt remains in the liquid portion of water underneath the ice, and the ice is pure water.
ground water and glaciers
pure and impure water. That is correct but pure water is distilled water and impure water is tap water, or natural water.
