The silicate anion in the mineral wollastonite is a chain of three SiO44−Si{O}_{4}^{4 -} tetrahedra, that share corners with adjacent tetrahedra. The charge of the silicate anion isThe silicate anion in the mineral wollastonite is a chain of three Si O _ 4 ^ 4 - tetrahedra, that share corners with

Options

  1. A-4
  2. B-8
  3. C-6
  4. D-2

Correct answer

C. -6

Step-by-step solution

The silicate anion in the mineral wollastonite is Si3O96−S{i}_{3}{O}_{9}^{6 -}. Hence, charge on it is -6.
