Question

write chemical name of 'x' 'y' and white percipitate​

Answer 1

Here X = Ba^2+ ( Barium ion)

and Y = Na2SO4 ( Sodium sulphate)

the white precipitate = BaSO4 (insoluble white precipitate)

Chemical equation for this reaction can be written as-

Ba^2+(aq) + Na2SO4 (aq) ----------> BaSO4 (s) + 2NaCl(aq)
