30 mLof 0.2 N BaCl2is mixed with40 mLof0.3 N Al2SO43. How many g ofBaSO4are formed?

Options:

Answer:
D
Solution:

BaCl 2 + Al 2 SO 4 3 → BaSO 4 + AlCl 3 Meq. Before Reaction 3 0 × 0 . 2 4 0 × 0 . 3 0 0 = 6 = 1 2 = 0 = 0 Meq. After Reaction 0 6 6 6

6 Meq. of BaCl2reacts with6 Meq. of Al2SO43to produce6 Meq. of BaSO4and6 Meq. ofAlCl3. 

∴   Meq. of BaSO4 formed = 6 =Wt.E × 1000;E=2332

wt. of BaSO4 formed =6 ×E1000=6 ×2332 × 1000=  0.70 g
