Question
Why do they mix well when there centres do not coincide
Q 2. A solution is formed when two similar substances are mixed. For example, water and salt form a solution, but water and oil do not. This is because:
• Water and salt are polar substances (wherein the centres of positive charge and negative charge do not coincide), so they can mix with each other.
• Oil is a non-polar substance, so it does not mix with water to form a solution.
