Density and specific gravity are often used to measure the relative concentrations of a known solvent and known solute.
A Hydrometer is a common device for measuring specific gravity of liquids.
Determine the mass of the solute before you add it to the water. If it is already dissolved, evaporate the water and determine the mass of the solute left behind.
It is called a solute, which is dissolved in a solvent
A solution is a clear mixture in which a substance is dissolved in water. (A colloidis a mixture having insoluble particles suspended in water)
evaporate the water
its rate of expansion is to great.
I would have thought it was air or water

Polar compounds are dissolved better in water.
Heat it.
The best method is chemical analysis.
No. Best example is CaCo3 (Chalk)
Two Factors are the type of material. The best material water moves through is a partially permeable membrane. Another factor is the substances dissolved in the water and the substances inside the material. There can also be if there are pores that are connected.
I don't know but drinking water from springs is better. Spring is OK, however the best water to drink would be water that is pH balanced. Have you seen the labels of bottled spring water? Most of them say they have so many "dissolved solids" in them. The less, the better. Dissolved solids are the stuff that couldn't get filtered out of it. The Problem they don't tell you what those dissolved solids are. It could be anything. The best water to drink I think is ionized alkaline water that's filtered.
Polar molecules are easily dissolved in water because water has also a polar molecule.
Yes the best example is nothing but salt dissolved in Water. It is a fast process when compared to crystalline substances dissolved in water. The rate of dissolving increases with increase in temperature.Example:Values are appropriate.Take one glass of water (at 28 deg C) and say max 100g of salt dissolved in it. When you take one glass of water ( at 60 deg C) the amount of salt dissolved is more.
The solubility of sodium acetate at 20 oC is 54,6 g/100 g water. If you add further solute and this is no longer dissolved the solution is supersaturated.
