1000 g of a mixture of Na2CO3,Na2SO4 and NaOH for complete neutralisation requires 511 g of HCl. The same mixture when reacted with excess of BaCl2 solution, produces 466 g of white precipitate of BaSO4. Calculate the mass percentage of NaOH in the mixture. (Given Molar mass of Na2CO3=106 g, Na2SO4=142 g, BaSO4=233 g, HCl=36.5 g and NaOH=40 g)

Answer» 1000 g of a mixture of $N a_{2} C O_{3}, N a_{2} S O_{4}$ and $N a O H$ for complete neutralisation requires 511 g of $H C l$ . The same mixture when reacted with excess of $B a C l_{2}$ solution, produces 466 g of white precipitate of $B a S O_{4}$ . Calculate the mass percentage of $N a O H$ in the mixture. (Given Molar mass of $N a_{2} C O_{3} = 106 g, N a_{2} S O_{4} = 142 g, B a S O_{4} = 233 g, H C l = 36.5 g a n d N a O H = 40 g$ )
