Aqueous solutions of barium chloride and sodium sulfate are combined at 25 °C. • 25.0 mL of 0.040 M BaCl

_2

• 35.0 mL of 0.060 M Na

_2

_4

The solubility‐product constant for BaSO

_4

at this temperature is

K_{sp}=1.1\times10^{-10}

. Assume volumes are additive. (a) Calculate the molar concentrations of Ba

^{2+}

and SO

_4^{2-}

immediately after mixing but before any precipitation occurs. (b) Determine the ionic product

Q

for BaSO

_4

under the conditions in part (a). (c) State whether a precipitate of BaSO

_4

will form. Justify your answer by comparing

Q

K_{sp}

. (d) Write the net ionic equation for any reaction that takes place or clearly indicate that no reaction occurs.
