What else can I help you with?
Use diffusion to explain what happens what happens when you drop a sugar cube in a cup?
When a cube of sugar is dropped in a cup of solvent like water or milk the molecules of sugar start diffusing from its block to the solvent by their own kinetic energy so as to make a uniform solution of the solute (sugar) and the solvent (water or milk).
Why will be change in the potato cube in concentrated sugar solution and distilled water respectively after an hour?
In the concentrated sugar solution, water will move out of the potato cube, causing it to shrink due to osmosis. In distilled water, water will move into the potato cube, causing it to swell due to osmosis.
Why does a sugar cube dissolve slower when not stirred?
When a sugar cube is not stirred, the surface area exposed to the solvent is limited, which slows down the rate of dissolution. Stirring increases the contact between the sugar cube and the solvent, allowing the sugar molecules to dissolve more quickly.
What factors can affect the rate of solvation?
Factors that can affect the rate of solvation include the nature of the solute and solvent, temperature, pressure, and the surface area of the solute particles. Additionally, the presence of impurities, stirring or agitation, and the polarity of the solute and solvent can also impact the rate of solvation.
How can you improve the solubility of a sugar cube in water?
You can improve the solubility of a sugar cube in water by crushing the sugar cube into smaller pieces to increase the surface area exposed to the water, stirring or agitating the solution to help the sugar dissolve faster, and heating the water to increase its ability to dissolve the sugar.

How does surface area effect solubility?
As the surface area of a solute increases, so does its solubility. This is because there is more area for the solvent to contact the solute and thus the solvent is able to interact with more of the solute at one time and dissolve it quicker. Think about a cube of sugar and a sheet of sugar, each the same mass. The sheet will dissolve quicker in water because so much of it is already interacting with the water molecules. The cube will not dissolve as fast because there are still molecules of sugar on the inside of the cube that will have to wait to interact with the water molecules.
The random movement of molecules in a solvent causes what in a cube of solid solute?
The random movement of molecules in a solvent causes the solvent molecules to collide with the surface of the solid solute. This results in the solute particles being surrounded by solvent molecules, leading to the process of dissolution.
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
Why will be change in the potato cube in concentrated sugar solution and distilled water respectively after an hour?
In the concentrated sugar solution, water will move out of the potato cube, causing it to shrink due to osmosis. In distilled water, water will move into the potato cube, causing it to swell due to osmosis.
How do you dissolve more sugar cube in a glass of saturated sugar solution?
By heating the saturated sugar solution, and then adding more sugar.
Why does a sugar cube dissolve slower when not stirred?
When a sugar cube is not stirred, the surface area exposed to the solvent is limited, which slows down the rate of dissolution. Stirring increases the contact between the sugar cube and the solvent, allowing the sugar molecules to dissolve more quickly.
When determine the molarity of a solution you must make sure that your answer is in terms of?
mol per dm cube
Why does grinding cause solutes to dissolve faster?
Because when you grind something up, you get powder. The surface area of powder is very high.Think about a sugar cube. As a cube, it's surface area is just that, the cube. When it's ground up, each grain of sugar can be attacked by the water from all sides. None of it is hidden in the centre of the cube.If you drop the cube into your tea, the water will dissolve the outer layer of sugar and then the next layer, then the next. If you pour powdered sugar into your tea, the water can dissolve it all at once. That's why the rate of dissolving is sped up. Increased surface area.
What sugar will desolve first sugar cube or granulated sugar?
A sugar cube will - one, sugar cubes are designed specifically to dissolve quickly into solvents such as tea, coffee, liquids to make solutions. Granulated sugar, on the other hand, is often a solute for solid solvents such as flour etc. However, the granulated sugar can be dissolved more quickly if stirred, which makes the solute particles attract to the solvent particles more efficiently.
Formula for finding distance?
if the concentration of sugar solution of volume of 360 cm3 cube is 0.785 mol/ dm3 has the mass of 25g of sugar present in the solution. work out for the mole of the sugar content in the solution.
How do you measure the volume of a sugar cube with a measuring cylinder?
Due to the sugar cube being soluble, you should use a solution which does not allow sugar to dissolve e.g. kerosene. Just follow the usual way to measure solids with a measuring cylinder and you will have the volume of the sugar cube
