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.
Ice is water (H2O) in it's solid state. It is a substance because it is entirely composed of one molecule and is not "mixed" with anything.
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.
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)
"Ice water" could either refer to water that has been chilled to the freezing temperature or just a container of water with ice floating in that is close to (but still above) that freezing temperature. Ice can be no warmer than the freezing point but can certainly be colder. If the solid (ice) is in equilibrium with the liquid ("ice water"), the ice will NOT be cooler, but as noted, if they are not really in equilibrium, you would expect the solid (ice) to be colder than the liquid water rather than the other way around.
Ice is a pure substance, not a mixture or compound. Ice is the solid form of water, with a chemical formula of H2O. It is made up of water molecules arranged in a crystal lattice structure.
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.
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 water is a compound.
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.
Ice is a pure substance because it is composed of only one type of molecule - water. Unlike mixtures which are made up of different substances, ice is made of a repeating pattern of water molecules arranged in a solid structure.
Melting ice works, because the ice sheet is fresh water.
Ice is water (H2O) in it's solid state. It is a substance because it is entirely composed of one molecule and is not "mixed" with anything.
Yes, because saline water has low freezing point as compare to distilled water or pure water.
Freezer ice is practically pure, having only the permitted impurities in tap water; but note that any thing is absolute pure.
Pure water forms a crystalline solid when it freezes, known as ice. Ice has a hexagonal crystal structure, where water molecules arrange themselves in a repeating pattern, creating the solid form we commonly see.
