Answer 1

Answer:

Treatment of sodium tungstate with hydrochloric acid gives the tungsten trioxide or its acidic hydrates: Na2WO4 + 2 HCl → WO3 + 2 NaCl + H2O.

Answer 2

Answer:

Treatment of sodium tungstate with hydrochloric acid gives the tungsten trioxide or its acidic hydrates: Na2WO4 + 2 HCl → WO3 + 2 NaCl + H2O.
