Everything is a substance. Radioactive chemical smog is a substance.
To answer the intent, however, ice is formed when water gets cold enough to form crystals. It is unusual in that this solid form attains greater volume than it's liquid form as a result of that crystalline matrix.
This was used extensively in the ancient quarying of rock. Water was poured into cracks in the stone in freezing weather, and the water froze and expanded it would force the crack apart and split the stone.
In a solution in which it cannot separate, this crystal formation does not occur, at least not correctly. More often, the pure water will freeze at a different temperature than anything mixed with it, therefore separating itself and floating in the remaining liquid.
This was a primitive way of distiling alcohol in cold climates. Apple cider, etc. was left outside overnight and the ice was removed in the morning, leaving behind the concentrated drink.

Is ice a mixture or a pure substance?
Ice is solid H2O so it is a pure substance, at least ideally.
Why ice is not a mixture?
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.
Is iced water a pure substance?
Iced water is not considered a pure substance; it is a mixture. While the water itself (H2O) is a pure substance when in its liquid or solid form, iced water contains ice (solid water) and liquid water, which coexist at 0 degrees Celsius. The presence of ice and liquid water together creates a heterogeneous mixture rather than a single pure substance.

Is ice a pure mixture?
If there is no salt or substance that makes it impure it is a pure mixture
Is ice a substance or mixture?
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.

Will a chunk of ice float higher than an ice cube?
A chunk of ice will float higher in water than an ice cube only if the ice chunk is larger than the ice cube.
Is lemonade a pure substance?
Lemonade is not a pure substance because it is a mixture of water, lemon juice, sugar, and possibly other ingredients such as ice. Each component can be separated from the mixture, indicating it is not a pure substance.
