Ch1 Review: Physical, inorganic and organic chemistry Flashcards
according to bronsted lowry
any reaction that involves a transfer of hydrogen ion is acid/base reaction
dissociation is
process in which mol’(or ion/complex) separate into smaller particles in a reversable manner.
electrolyte is
substance whose aq solution conduct electricity (acid,base and salt)
osmosis is
process by which molecules of a solvent pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
osmotic pressure
amount of pressure needed to stop net movement of solvent
solubility is
degree to which a substance dissolves in a solvent to make a solution
mole is

molar mass

mole

two acid theories

what is Ka?

Electrolytes:
substances which dissociate to ions during interaction with molecules of a polar solvent and are capable of conducting an electric current in the solution

In extremely diluted solutions of strong electrolytes, their ions are in a sufficient distance from each
other and their charges are not mutually influenced. Because of electrostatic ion-ion interactions in the
solution, the more concentrated solutions of strong electrolytes behave differently from an ideal state.
Due to electrostatic forces the ions are less mobile and the solution behaves as if there were a lower
number of ions. These differences are expressed by correction coefficients.
The product of the activity coefficient and concentration then gives the activity of ions ai
The unit of activity is the same as that for concentration, to which it is related (mol l−1 or mol kg−1 of H2O).
