How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?
The vapor pressure of pure water will be higher than that of an aqueous solution of sodium chloride at the same temperature because the presence of sodium chloride reduces the number of water molecules available to evaporate, lowering the vapor pressure of the solution. In other words, the solute particles in the solution interfere with the evaporation of water molecules, resulting in a lower vapor pressure compared to pure water.
Is soil in water solution suspension or colloid?
Soil in water is typically a suspension, as the soil particles will settle over time due to gravity. If the soil particles are very fine, it may exhibit some colloidal properties due to the interactions between the particles and the water molecules, but it is still primarily considered a suspension.
Why does ammonium nitrate dissolve in water?
Ammonium nitrate dissolves in water because it is a highly water-soluble salt. When it comes into contact with water, the polar water molecules interact with the charged ions in ammonium nitrate, causing it to dissociate into ammonium and nitrate ions, which become uniformly distributed in the water solution.
Is ammounium chloride and water a physical or chemical change?
When ammonium chloride(NH4Cl) is dissolved in water the solvation process itself is a physical change, NH4Cl changes from one of its state (crystalline) to solution, where NH4+ and Cl- ions are surrounded by water molecules.
How could a solution of copper chloride and water be separated into starting substances?
The solution of copper chloride and water can be separated by a process called evaporation. By heating the solution, the water will evaporate, leaving behind crystallized copper chloride. These crystals can then be filtered out, resulting in the separation of the copper chloride and water.
Can copper sulphate be separated from its solution by crystallization?
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
A colliod has smaller particles than a solution?
No, a solution has much smaller particles than a colloid. In a solution the particles are individual atoms, molecules, or ions.
What are the dissolved particles in a solution containing a molecular solute?
The dissolved particles in a solution containing a molecular solute are individual molecules of the solute. These molecules are dispersed and surrounded by the solvent molecules, forming a homogenous mixture.
How are the particles of the solution like?
In a solution, the particles are evenly distributed throughout the solvent. These particles can be molecules, ions, or atoms that are in a homogeneous mixture with the solvent. The size of the particles in a solution is typically smaller than those in a suspension or colloid.
Does a solution have big particles?
No, a solution consists of uniformly distributed particles that are too small to be seen with the naked eye. The particles in a solution are typically individual atoms, ions, or small molecules.
Why does salt separated from a salt water solution look different than the salt that dissolved in the water?
The separated salt is a crystalline solid; the dissolved salt is dissociated in ions.

Explain how you could determine that brass is a solution and not a colloid or suspension?
Brass is a solution as it is homogenous in composition. In cannot be separated out. The particles are as one and do not hang where there could be spun out. Since they cannot be separated, brass is a solution.
What happens to particles when they are dissolved?
When particles are dissolved in a solvent, they disperse evenly throughout the solvent and become surrounded by solvent molecules. This results in the particles being separated from each other and mixed uniformly throughout the solvent, forming a solution.
What is the movement of particles in a dilute sugar solution?
Molecules are in a permanent motion.
What is the dissolved particles in the solutions?
Solvent
