Why does water dissolve other polar substances very easily?
Why does water dissolve other polar substances very easily?
- Water molecules are neutral and react with other polar substances.
- Water molecules repel other polar substances.
- Positive ends of other polar molecules are attracted to negative ends of water molecules. (correct)
- Water molecules are attracted to non-polar substances.
What causes polar substances to mix uniformly with water?
What causes polar substances to mix uniformly with water?
- Attraction between positive ends of polar substances and the negative ends of water molecules. (correct)
- Repulsion between water and the polar substances.
- Uniform molecular size of polar substances.
- Neutral charge of polar substances.
Why are polar substances easily mixed with water?
Why are polar substances easily mixed with water?
- As the positive ends of polar substances are attracted to the negative ends of water molecules. (correct)
- Because water has similar properties to non-polar substances.
- Due to repulsion between molecules of different substances.
- Since polar substances are inert in water.
