Alloys - ANS - An alloy is a mixture of two elements, one of which is a metal.
Alloys often have properties that are different to the metals they contain. This
makes them more useful than the pure metals alone. For example, alloys are
often harder than the metal they contaiN
\Colloid - ANS - In chemistry, a colloid is a mixture in which one substance of
microscopically dispersed insoluble particles is suspended throughout another
substance.
\Concentrated solution - ANS - A dilute solution is one in which there is a
relatively small amount of solute dissolved in the solution. A concentrated
solution contains a relatively large amount of solute
\Concentration - ANS - In chemistry, concentration is the abundance of a
constituent divided by the total volume of a mixture. Several types of
mathematical description can be distinguished: mass concentration, molar
concentration, number concentration, and volume concentration
\Dilute solution - ANS - Dilution is the process of decreasing the concentration of
a solute in solution, usually simply by mixing with more solvent. To dilute a
solution means to add more solvent without the addition of more solute. ... If one
adds 1 litre of water to this solution the salt concentration is reduced
\Heterogeneous mixtures - ANS - A heterogeneous mixture is simply any mixture
that is not uniform in composition - it's a non-uniform mixture of smaller
constituent parts. Using various means, the parts in the mixture can be separated
from one another.
\Homogeneous systems - ANS - A homogeneous mixture has the same uniform
appearance and composition throughout. Many homogeneous mixtures are
commonly referred to as solutions. A heterogeneous mixture consists of visibly
different substances or phases. The three phases or states of matter are gas,
liquid, and solid.
\Insoluble - ANS - BSL Chemistry Glossary - insoluble - definition. Definition: An
insoluble substance is a substance (solid) that will not dissolve in a solvent even
after mixing (eg; sand and water).

\Mixture - ANS - In chemistry, a mixture is a material made up of two or more
different substances which are mixed but are not combined chemically. A mixture
refers to the physical combination of two or more substances in which the
identities are retained and are mixed in the form of solutions, suspensions, and
colloids.
