Halo-halo Flashcards
is the equilibrium constant for a solid substance dissolving in an aqueous solution (heterogenous equilibria). It represents the level at which a solute dissolves in solution.
Solubility product constant
is
the concentration of
solute in a saturated
aqueous solution.
Molar solubility
any ion in the solution that is
common to the ionic compound being dissolved.
Common ion
Says that if an external stress is applied to a system at equilibrium, the system adjusts in such a way that the stress is partially offset as the system reaches a new equilibrium
position.
Le Chatelier’s Principle
indicates the closeness of
the measurement to its true or
accepted value (Skoog et al., 2020)
Accuracy
describes the
reproducibility of measurements or
the closeness of the results
Precision
is the absolute error divided by the true
value expressed in percent, ppt, or ppm.
Relative Error
causes data
to be scattered more or less
symmetrically around a mean
value.
Random Error
causes the mean of a set of
data to differ from the accepted
value
Systematic error
occasionally
occurs, are often large, and may
cause a result to be either high or
lo
Gross Errors
are caused
by imperfections in measuring devices
and instabilities in their components.
Instrument errors
nonideal
chemical or physical behavior of the
reagents and reactions upon which
an analysis is based.
Method errors
Measurements
requiring personal judgment (personal
limitations). Judgments of this type are
often subject to systematic, unidirectional
errors
Personal errors
independent of
the size of the sample being analyzed.
Constant errors
increased or
decreased in proportion to the size of the
sample
Proportional errors
