Question

Salt(A) produces golden yellow flame on flame test. Aqueous solution of (A) produces a white precipitate with barium chloride solution. The precipitate is insoluble in dilute mineral acids. On thermal decomposition in presence of $SiO_{2}$ , (A) forms a salt (B) and gas(C). When B is treated with an acid(D), Salt (B) form NaF and other products. What is the molar mass of (D) in $g mol^{- 1}$ units?

Answer:

20

Solution:

$A = Na_{2} SO_{4} 10 H_{2} O, B = Na_{2} SiO_{3}, C = SO_{3}, D = HF, PPt = BaSO_{4}$
