Hydrogen sulfide
________ is reacted with the unknown acidic solution after the chloride precipitates have been removed by filtration.
Filtration
________ is used to remove these precipitates from the solution as well.
stoichiometric coefficient
The product of the molar concentrations of the constituent ions, each raised to the power of their ________ in the equilibrium equation, is the solubility product of a compound.
hydrogen ion
The ________ and hydroxide ion concentrations are very low in a strong- acid titration at the equivalence point (about 1 to 10- 7 M); therefore, the added value is one drop.
weak acid or base
The ionization of a(n) ________ is suppressed by the presence of a common ion.
equivalence point
As the ________ is located on the steep part of the curve, the pH on the ________ is inserted in the range that changes the color of the indicator.
PH
________ has little effect on the solubilities of salts containing non- hydrolyzing anions.
Al
________ (OH) 3 is increased solubility in a medium by the formation of a complex ion ________ (OH) 4 − Al (OH) 3 acting as Lewis acid and OH− acting as the Lewis base.
constant Kf
The formation ________, which is the equilibrium constant for complex ion formation, is a measure of a metal ion's tendency to create a specific complex ion.
buffer solution
A(n) ________ is made up of two components: (1) a weak acid or base and (2) its salt; both must be present.
