ie: SO4-2 = electracal charge of -2 = Equivalent charge of 2 because equivalent is the absalute value of the electracal charge.
Osmosis
Least to most
Water molecules move through a semipermeable membrain from the solution with the lower solute concentration into a solution with the higher solte concentration.
Hypertonic solution
"Greater then" causes crenation, to shrink and shrivel.
Isotonic Solution
"Equal to" or normal
RBC = 0.9% NaCl
5.0% Glucose
Hypotonic Solution
"Less Then" causes cells to hemolysis, (swells and bursts).
Hemolysis
Swell & Burst
Crenation
Shrink & shrival
Hydrogenation
Addition of H2 or 2H2(used with pt catalist to break double bonds (H2) and triple bonds (2H2)).
