Many common weak bases are derivatives of , where one or more of the hydrogen atoms have been replaced by another substituent. Such reactions can be generically symbolized as where is the base and is the conjugate acid. The equilibrium-constant expression for this reaction is where is the base ionization constant. The extent of ionization, and thus the strength of the base, increases as the value of increases. Part A If for is 3.0×10-6, what is the of a 0.175 aqueous solution of ? Express your answer numerically. = Part B If for is 3.0×10-6, what is the percent ionization of a 0.325 aqueous solution of ? Express your answer numerically to three significant figures. percent ionization = Part C If for is 3.0×10-6 , what is the the for the following reaction? Express your answer numerically to two decimal places. =
