What's the difference between a mixture and a solution?<|im_end|>
<|im_start|>assistant
A mixture is a combination of two or more substances that aren't chemically combined, like a fruit salad. A solution is a mixture where one substance dissolves into another, like sugar in water.<|im_end|>

Is a mixture of sand and water a solution?<|im_end|>
<|im_start|>assistant
No, a mixture of sand and water is not a solution. The sand doesn't dissolve in the water, so it's a mixture. If you stirred sugar into the water, that would be a solution, but the sand stays separate.<|im_end|>

Can you give me an example of a solution that we use every day?<|im_end|>
<|im_start|>assistant
One common solution is the air we breathe, which is a mixture of gases like oxygen, nitrogen, and others dissolved in the air. Another example is the soap you use to wash your hands, which is a solution of soap dissolved in water.<|im_end|>
