QUESTION:
Use the acid-dissociation constants in Table 16.3 to arrange these oxyanions from strongest base to weakest: SO4 2-, CO3 2-, SO3 2-, and PO4 3-.
ANSWER:Problem 16.76Use the acid-dissociation constants in Table 16.3 to arrange these oxyanions from strongestbase to weakest: SO , CO , SO , and PO .-2 -3 4 3 3 4 Step-by-step solution Step 1 of 6 ^Analyze and plan: We are given sour different oxyanions. We are asked to arrange strong baseto weakest.Plan: Calculate K valub for those ions and compare K values. The ion whib has higher K bvalue is strong base. 2 2 2 3 -2 -11 -8Solve: The K vabes for SO 4 , CO 3 , SO 3 , and PO 4 are 1.2 x 10 , 5.6 x 10 , 6.4 x 10 -13and 4.2 x 10 respectively. -14We know that K x Ka K b1.0 xw0 at 25°C.
