chem Flashcards
it tells
how many molecular weights of solute are dissolved in
each “Liter” of solution
) Molar (M)
In the clinical laboratory, “water” always refers to
distilled water
contains more than the maximum amount
of solute that can be dissolved at that temperature
Supersaturated Solution
how much solute is dissolved
in one hundred parts (usually 100 ml) of the solution
Percent solutions
s a homogeneous part of a system separated
from other parts by physical boundaries.
Phase
material containing two or more substances
Mixture
the molecules or ions are so small (less
than 1 nm) that they cannot be seen and will remain
dispersed in the liquid
a true solution
When water is the solvent we say it is an
aqueous solution
Particular kind of matter with fixed
composition ,may be present in different states or phases
Substance
the solvents has only a small quantity of solute
dissolved in it
Dilute solution
The dissolving substance
solvent
………………… gives a liquid fluidity and causes it to take……………… in which it is stored.
Particle mobility, the shape of the container
it tells how many
equivalent weights of solute are dissolved in a “Liter” of
solution.
Normal (N)
The solvent has a large quantity of solute
dissolved in it
Concentrated solution
discrete, tiny, fundamental particles
atoms
The substance being dissolved in the solvent
solute
is anything that has mass and occupies space.
matter
This tells how many molecular weights of solute per Kg of
solvent.
Molal ( m )
It is a homogenous mixture of two or more substances
Solution
contains the maximum amount of solute that will
dissolve at that temperature.
Saturated solution
The elements were first arranged in this way in 1869 by ……………………, a Russian scientist.
Dimitri
Mendeleev
each box there is the symbol for the element
and, above it, a number called the
atomic number.
The elements in the modern periodic table are arranged in
order of increasing …………………
atomic number.
atoms of an element must be capable of
having ………….numbers of
neutrons
