Yes, ice is 100% water, but in a solid state.
Water, in its liquid form, is composed of hydrogen and oxygen molecules (H₂O). When water freezes, the molecules arrange themselves into a crystalline structure, forming ice. This structure is less dense than liquid water, which is why ice floats.
While ice is 100% water, it may contain impurities like dissolved minerals or air bubbles, but these are typically insignificant in terms of overall composition.
Ice is simply water in a different state of matter. The chemical composition remains the same, only the physical arrangement of the molecules changes.
In summary:
- Ice is formed when liquid water freezes.
- The chemical composition of water remains the same in both liquid and solid states.
- Ice is essentially water in a solid form.
