A Soluble Solution: Science Fair Project

799 words - 3 pages

My science fair project is to find the solubility of salt and sand.Solubility is the measure of how much solute can dissolve in a given solvent at a given temperature.A solute is the part of a solution that is dissolved by a solvent.A solvent is the part of a solution that is usually present in the largest amount and dissolves a solute.A solution is a mixture containing a solvent and at least one solute that has the same properties throughout; a mixture in which one substance is dissolved in another.
The solubility of a substance depends on the used solvent and the temperature and pressure. Solubility results from simultaneous and opposing dissolution and phase joining.To dissolve is to break into smaller pieces.Even if something’s dissolved, the solute is still there.When something is insoluble, you can’t dissolve it, and you can see it floating on the surface of the water.
Solubility should not be confused with the ability to dissolve a substance.The solution might occur not just because of dissolution, but of chemical reaction.For most solids dissolved in liquid water, the solubility increases up to 100 degrees celsius.Solubility is commonly expressed as a concentration.The solubility of a substance is determined by using water, and mixing it with the solute.
A chemical is a substance used in a chemical process.Everything that has mass is a chemical.Anything that is matter is a chemical. Filtration is the process of separating solid particles from fluids.To evaporate is to change from a solid or liquid to vapor.Alcohol is soluble in water.However, oil is insoluble in water.
All compounds of the alkali metal elements are soluble.All ammonium salts are soluble.All hydroxide compounds are insoluble.All sulfide compounds except for alkali metals and earths are insoluble. For solution, the chemical you a is a solute.
Rather often, the solvent is a liquid; pure substance or mixture.There is also solid solutions though.The solution is rarely in gas form.Soluble and insoluble items don’t mix.A mixture of chemicals is a blend of two or more different kinds of chemicals where individual chemicals remain separate.
Matter is basically anything made up of atoms and molecules.Any form of matter can be soluble.Forms of matter can be called phrases.The solute(if soluble)spreads around in water.If two things are immiscible, they will not mix or...

If scientists do not have knowledge to find cures for diseases the quality of living that we have
