38. The dependence of the specific electrical conductivity of a BaCl2 solution on concentration is expressed as follows:
Cn, mol/l 0.001 0.002 0.003 0.004 0.005
æ, Sm•m–1 0.0134 0.0264 0.0391 0.0517 0.0640
How many milligrams of a solution of barium chloride, the electrical conductivity of which is 0.0455 S·m–1, should be taken to precipitate the sulfate ions contained in 50 ml of 0.002 N. sodium sulfate solution?
