Sodium chloride and barium chloride?
Sodium chloride chemical formula unit is NaCl.
Barium chloride chemical formula is BaCl2.
Barium chloride reacts sodium sulfate in aqueous solution to give soluble sodium chloride and insoluble barium sulfate how would you isolate the barium sulfate?
Barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride?
Barium Chloride + Sodium Sulfate --> Barium Sulfate + Sodium Chloride BaCl2 + Na2So4 --> BaSO4 + 2NaCl It's called a Double Displacement reaction because Barium(Ba2+) and Sodium(Na+) displaces each other from their original anions. It's also called a Precipitation reaction because a white precipitate is formed after the reaction due to Barium Sulfate(BaSO4) as it is insoluble.
If both are in solutions, barium sulfate would precipitate out of the solution - unless if the barium chloride solution is dilute enough that only a small amount of barium sulfate will form, thus remaining soluble in the solution. The remaining sulfate will remain in the solution as wellas sodium and chloride.
Barium sulfate is much less soluble in water than either of sodium chloride and sodium chloride. When mixed, the solubility of the barium sulfate is exceeded. The barium sulfate then precipitates as fine solids, which remain suspended but scatter light to produce the milky look. Added: Na+ (sodium ion) and Cl- (chloride ion) don't react, Only Ba2+ and SO42- do so by forming precipitate: SO42- + Ba2+ --> (BaSO4)s
This insoluble substance formed is known as a precipitate. Any reaction that produces a precipitate can be called a precipitation reaction. Na2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2NaCl(aq) (Sodium (Barium (Barium (Sodium sulphate) chloride) sulphate) chloride) The other product formed is sodium chloride which remains in the solution. Such reactions in which there is an exchange of ions between the reactants are called double displacement reactions. posted by hari
