Question

What volume of 5M $Na_{2}SO_{4}$ must be added to 25 mL of 1 M $BaCl_{2}$ to produce 10 g of $BaSO_{4}$ ?

Answer 1

Solution

(1) : $Na_{2}SO_{4} + BaCl_{2} \rightarrow BaSO_{4} + 2NaCl$

No. of moles of

$BaSO_{4} = \frac{w}{M} = \frac{10}{233} = 0.0429$

$\therefore$ No. of moles of $Na_{2}SO_{4}$ needed

$= 0.0429 = \frac{M \times V}{1000}$

$v = 8.58$ Ml
