Science / Chemistry / Sol: A colloid with solid particles suspended in a liquid. Examples are protoplasm, starch in water, and gels.

Standard Solution

Science / Chemistry / Standard Solution: A solution of precisely known concentration. MORE

Acidic Solution

Science / Chemistry / Acidic Solution: A solution in which the hydrogen ion activity is higher than that of the hydroxide ion, when the solvent is water. MORE

Aprotic Solvent

Science / Chemistry / Aprotic Solvent: A solvent that does not act as an acid or as a base; aprotic solvents don't undergo autoprotolysis. Examples are pentane, pet ether, and toluene. MORE

Absolute Error

Science / Chemistry / Absolute Error: Absolute uncertainty. Compare with relative error. The uncertainty in a measurement, expressed with appropriate units. For example, if three replicate weights for an object are 1.00 g, 1.05 g, and 0.9 MORE

Crystalline Solid

Science / Chemistry / Crystalline Solid: A solid that has a repeating, regular three-dimensional arrangement of atoms, molecules, or ions. MORE

Solvent Extraction

Science / Chemistry / Solvent Extraction: Solvent extraction is a method for separating mixtures by exploiting differences in the solubilities of the components. For example, a coffee machine extracts the soluble components of ground coffee w MORE
