the temperature at which the solution freezes is lowered.
Adding more solute to a saturated aqueous solution causes the excess solute to precipitate out of the solution as solid particles. This process is known as precipitation and helps to decrease the concentration of the solute in the solution, allowing for more solute to dissolve.
Adding solute to a solution increases the mass of the solution because the solute particles become dispersed in the solvent, increasing the total mass of the mixture. The mass increase is directly proportional to the amount of solute added.
Adding a solute to a solvent will increase the mass of the solution because the solute molecules are being introduced, contributing to the total mass. The increase in mass will be proportional to the amount of solute added.
Adding a solute to a solvent lowers the freezing point of the solution, a phenomenon known as freezing point depression. This occurs because the solute particles disrupt the formation of the solid lattice structure of the solvent, requiring a lower temperature to achieve freezing. The extent of this effect depends on the concentration of the solute and its properties. As a result, solutions freeze at temperatures lower than that of the pure solvent.
Adding a solute to a solvent raises the boiling point of the solution, a phenomenon known as boiling point elevation. This occurs because the presence of solute particles disrupts the formation of vapor bubbles, requiring more energy (higher temperature) for the solution to boil. The extent of this boiling point increase depends on the concentration of the solute and the properties of the solvent, as described by Raoult's law and the colligative properties of solutions.
The addition of solute to a solvent concentrates the overall solution. A nice example is the laundry detergent. Some (less) concentrated detergents are less viscous, while highly concentrated detergents are more viscous (greater density). Also, adding more solute to a solvent can lower the freezing point.
The solution freezes at a lower temperature and boils at a higher temperature.
Nothing more can be added to a saturated solution - the liquid is literally 'full up' with the solute being dissolved, so if you carry on adding the solute, it will not dissolve and the solution will not become any more concentrated. A concentrated solution has a very large amount of the solute in it (there is more solute than solvent), but it has not yet reached the point where no more solute can be dissolved. If you keep adding to it, the solute will dissolve.
Adding more solute the solution become supersaturated.
Yes, you can increase the concentration of a solution by adding more solute. This process involves dissolving additional solute in the solvent, which raises the ratio of solute to solvent. However, there is a limit to how much solute can be added, known as the solubility limit, beyond which the solute will not dissolve and will remain as a solid.
