Why does stirring speed up dissolve?
It speeds up dissolving because for example when you have a sugar cube and you drop it in water it will dissolve very slowly because only the outside layer is getting exposed to the water or solvent. But when you stir it you are making the outside layer get dissolved faster so the next layer could get dissolved and this will go on till it is all dissolved
In chromatography how are the sunstances carried up the paper?
The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others.
Do water dissolve more substance than any other liquid?
No, not all substances dissolve in water. Substances that are nonpolar, meaning that they don't have a dipole moment, will not be able to dissolve in water because water is a polar solvent. Only polar solutes will dissolve in polar solvents. Oil is an example of such a substance that is nonpolar and does not dissolve in water. There are also ionic compounds that are insoluble in water, such as silver bromide (AgBr), potassium sulfide (K2S), and lead(II) sulfate (PbSO4).
How would you then make it a supersaturated solution?
To make a supersaturated solution, you would first dissolve the maximum amount of solute in the solvent at an elevated temperature to increase solubility. Then, slowly cool the solution down without disturbing it to prevent the excess solute from precipitating out, creating a supersaturated solution.
What is the best way to make a supersaturated solution?
Heat the solution
How can determine if no more solute can dissolve in a solvent?
If no more solute can dissolve in a solvent, it means the solution is saturated. You can determine this by observing if there is excess solute at the bottom of the container that does not dissolve even with additional stirring. Another way is by conducting a solubility test, where you slowly add more solute to the solvent while stirring until it no longer dissolves.
Do solutions dissolve solids?
yes but it depends on the temperature of the solid e.g. steel must be very hot to absorb any solution as a cooling agent. like block and wood they do but very slowly.
How do you dissolve gelatine leaves?
Place them is water or another liquid and slowly heat until they have dissolved.
What can be done to a substance to make it dissolve faster in a solvent?
Increase its surface area exposed to the solvent is the easiest way to (e.g break or cut the material going to be dissolved). Or for some, you can increase the temperature, or add it to the solvent slowly.
Why can the pigment spot on chromatography paper not be submerged in solvent?
The pigment spot on chromatography paper should not be submerged in solvent because it will result in spreading and mixing of the pigments, making it difficult to distinguish them. Instead, the solvent should be allowed to slowly travel up the paper by capillary action, separating the pigments based on their solubility and mobility.
Do laxatives dissolve quickly or slowly in the stomach?
slowly
Why does the liquid wax move up the oil slowly?
The liquid wax moves up the oil slowly due to capillary action. Capillary action occurs because of the adhesive and cohesive forces between the liquid wax and the oil, causing the liquid to move in opposition to gravity. This movement is more pronounced in narrow spaces like the wick of a candle.
How does cold liquid affect the rate at which a substance dissolves?
Colder temperatures make molecules move more slowly. Since molecules are moving more slowly, they are less likely to 'bump' into each other and interact. When you are trying to dissolve a substance, you want as many interactions as possible between the substance you want to dissolve and the liquid you are trying to dissolve it in. Since the cold temperature slows down the rate of these interactions, it slows down the rate at which a substance dissolves.
Why do larger sugar grains take longer to dissolve?
Larger sugar grains have less surface area exposed to the surrounding liquid, so it takes longer for the liquid to penetrate and break down the sugar crystals. As a result, the larger grains dissolve more slowly compared to finer sugar grains which have more surface area available for the liquid to act on.
What is the process of gas slowly changing to liquid?
condensation is the process of gas slowly turning to a liquid.
Do solutions dissolve?
yes but it depends on the temperature of the solid e.g. steel must be very hot to absorb any solution as a cooling agent. like block and wood they do but very slowly.
