Which of the following statement is wrong?

Options

  1. AThe two sulphur atoms in the thiosulphate ions occupy equivalent positions
  2. BIce results from cooling of water whereas snow results from cooling of vapours to solid
  3. CFormation of ice is solidification whereas formation of snow is Hoar frost
  4. DIce sublimes on moon

Correct answer

A. The two sulphur atoms in the thiosulphate ions occupy equivalent positions

Step-by-step solution

16 35 S + S O 3 2 - → [ 16 35 S S O 3 ] 2 - → 2 H + 16 35 S + H 2 O + S O 2 The tagging technique confirms that two S atoms in S 2 O 3 2 - ions do not occupy equivalent positions. Also, w a t e r → Solidification i c e i c e → sublimation v a p o u r → H o a r frost i c e i c e → v a p o u r Ice sublimes on moon and directly convert into water vapour.
