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 M e q . o f B a C l 2 reacts with 6 M e q . o f A l 2 S O 4 3 to produce 6 M e q . o f B a S O 4 and 6 M e q . o f A l C l 3 . ∴ M e q . o f B a S O 4 f o r m e d = 6 = W t . E × 1000 ; E = 233 2 w t . o f B a S O 4 f o r m e d = 6 × E 1000 = 6 × 233 2 × 1000 = 0.70 g
