Hydrogen sulfide
________ is reacted with the unknown acidic solution after the chloride precipitates have been removed by filtration.
sodium hydroxide
Adding ________ to a sample can reveal the presence of NH4 +.
Filtration
________ is used to remove these precipitates from the solution as well.
BaCO3
Cations in Group 4 Following the removal of all group 1, 2, and 3 cations from the solution, sodium carbonate is added to the basic solution to precipitate Ba2+, Ca2+, and Sr2+ ions as ________, CaCO3, and SrCO3.
weak acid
The ionization of a(n) ________ or base is suppressed by the presence of a common ion.
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.
AgCl
Thus a decrease in salt solubility (________) in solution is the effect of adding 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.
neutral solutions
In acidic and ________ phenolphthalein is colorless but in basic solutions reddish pink.
PH
________ has little effect on the solubilities of salts containing non- hydrolyzing anions.
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.
