A quantity of 16.0 g of solid sulphur is first oxidized to and then it is divided into two equal parts. One part is sufficient for complete decolourization of 250 ml of acidified solution. Another part is oxidized to and the formed is sufficient for complete precipitation of all present in 200 ml solution as . Which of the following statements is/are correct? (S = 32, Ba = 138)
Options:(select one or more)
Answer:
A, C, D
Solution:
16.0 g S = 0.5 mol 0.5 mol , split into 0.25 mol halves. First half: ( = 2) gives 0.5 g-eq, so ( = 5) = 0.1 mol in 250 ml = 0.4 M - (a) true. Second half: 0.25 mol 0.25 mol = 0.25 234 = 58.5 g - (c) true; = 0.25 mol in 200 ml = 1.25 M, not 0.125 M - (b) false. Equivalents: 0.5 g-eq vs 0.25 mol 2 = 0.5 g-eq - equal, (d) true. Hence (a), (c), (d).
