A Result of the Common-Ion Effect Is ________

question 48

Multiple Choice

A result of the common-ion effect is ________.

• A)that some ions, such as Na⁺ (aq), frequently appear in solutions but do not participate in solubility equilibria
• B)that common ions, such as Na⁺ (aq), don't affect equilibrium constants
• C)that the selective precipitation of a metal ion, such as Ag⁺, is promoted by the addition of an appropriate counterion (X^-)that produces a compound (AgX)with a very low solubility
• D)that ions such as K⁺ and Na⁺ are common ions, so that their values in equilibrium constant expressions are always 1.00
• E)that common ions precipitate all counter-ions
