Question

12. Raven is vigorously stirring a mixture of sand and water. She says, “As long as I keep stirring, the sand stays dissolved in the water.” Do you agree with Raven? Explain why or why not.

Yes, the given statement by Raven is correct. As long as the mixture of sand and water is kept stirring , the sand stays dissolved in the water and this mixture of solution is called suspension mixture.

$There \: are \: 3 \: types \: of \: mixtures \: - \\ 1. \: solution \\ 2. \: suspension \: mixture \\ 3. \: colloidal \: mixture$

1. Solution - A solution is a homogeneous mixture where one substance is dissolved in another substance. The solute dissolves in the solvent. The solvent is a liquid or gas, and the solute can be a solid, liquid or gas.

2. Suspension mixture - In this mixture, the suspended particles are visible under a microscope and will settle over time if left undisturbed.

3. Colloidal mixture - In this mixture, the suspended particles are smaller and do not settle down when left undisturbed.
