Sagot :
Answer:
1. Our air is a homogeneous mixture of many different gases and therefore qualifies as a solution. Approximately 78% of the atmosphere is nitrogen, making it the solvent for this solution.
2.When one substance dissolves into another, a solution is formed. A solution is a homogeneous mixture consisting of a solute dissolved into a solvent . The solute is the substance that is being dissolved, while the solvent is the dissolving medium.
3. If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.
Answer:
1. The substance that is present in the largest amount is called the solvent. It acts as the dissolving medium.
2. The substance that is present in the smaller amount is called a solute. The solute is the substance that is being dissolved.
3. Saturated solution is a solution that contains all of a substance capable of dissolving; a solution of a substance in equilibrium with an excess undissolved substance. If more solute is added to the solution and the solute remains undissolved, then it shows that the solution is saturated.
