Question

In one sample of brass, the following ingredients were found: Copper (70%) and zinc (30%). Identify the solvent, solute and solution from these.

Answer 1

Hint: We can define a solution is a homogeneous combination of two or more substances. A solvent and a solute are components present in a solution. The component of the solution, which dissolves the other component in it, is known as the solvent. The component of the solution, which is dissolved in the solvent is called the solute.

Complete step by step answer: We can say the solution is a mixture of solute and solvent.
We know that brass is made of copper with zinc. It is a solid solution that contains zinc and other metals as solute, and copper acts as the solvent.
So, here the solute is zinc, the solvent is copper and the solution is brass.
Based on the type of solvent, we can classify solution as aqueous solution, and non-aqueous solution. Aqueous solution contains water as the solvent, and solute is dissolved in water. Examples of aqueous solutions are salt in water, sugar in water etc. In a non-aqueous solution, water is not solvent. The solute is dissolved in solvent instead of water. Examples of non-aqueous solutions are iodine in carbon tetrachloride, phosphorus in ethyl alcohol, and sulfur in carbon disulfide.
Some common examples of solutions are the sugar in water and salt in water solutions, soda water, etc. In a solution, all the components are seen as a single phase. The particles are evenly distributed.

Note: We can classify solution into two types depending on the amount of solute added to the small amount of solvent as dilute solution and concentrated solution.
-If a small amount of solute is added to a larger amount of solvent, then the solution is called a dilute solution.
-If a larger amount of solute is dissolved in a smaller amount of solvent, then the solution is called a concentrated solution.
