Pepper will not dissolve in water.
Add the mixture into water and stir to dissolve the sugar. Pour the watery mixture into another container, using a paper filter to catch the pepper. If you would like to have the sugar back into solid form, simply evaporate the water.
Almost impossible, pepper doesn't dissolve as quickly as sugar though. Although you'll be without sugar. You could try shaking it but I doubt that will work. Best just to use it as it is for times you need both. They are both cheap, just chunk it.
Dissolve the mixture in pure water. Run the water through a filtration system. All the pepper should be trapped in the filter and you will need to allow this to dry. The water that runs through the filter should contain all the sugar - in solution. It will be necessary to allow this water to evaporate - either in its own time or by evaporation. However, you may end up with sugar crystals that are quite different (in size) from those in the sugar-pepper mixture.
Sugar solution
Pepper and water is not a solution, it is a mixture because the pepper will not dissolve. If you're wondering if salt and water is a solution, it is because it's the solution saltwater and the salt does dissolve unlike the pepper.
No, a mixture of pepper and water would not be considered a solution. In chemistry, a solution is a homogeneous mixture where one substance (the solute) is dissolved in another substance (the solvent). In this case, pepper does not dissolve in water, so it would not form a solution. Instead, it would be considered a suspension, where the pepper particles are suspended in the water but do not dissolve.
Pure sugar is a compound, which is a pure substance. If you dissolve sugar in water, you will have a homogeneous mixture, which is a solution.
Dissolve the sugar in water and then evaporate the water
Pour the mixture into enough water that all the sugar will dissolve. Sand does not dissolve in water, so the sand will settle to the bottom of the solution and then you can sift the sand out of the solution. Then you will just have sand and sugar water, which can evaporate, leaving the sugar behind in the container.
Yes, water can be used to separate sand and sugar. Sugar will dissolve in water, while sand will not. By adding water to the mixture, the sugar will dissolve and can be separated from the sand by filtration or evaporation.
You can use the property of solubility in water to separate sugar from a mixture. Since sugar is soluble in water, you can dissolve the mixture in water and then use filtration or evaporation to separate the sugar from the other components.
To separate a mixture of sugar and sulfur, you can use water to dissolve the sugar while leaving the sulfur undissolved. First, add water to the mixture and stir, allowing the sugar to dissolve completely. Then, filter the mixture; the dissolved sugar will pass through the filter paper, while the sulfur remains on the paper. Finally, evaporate the water from the collected solution to obtain the sugar.
