Silica gel contains [CoCl4]2– as an indicator when activated, silica gel becomes dark blue while upon absorption of moisture, its color changes to pale pink. This is because:           
  • a)
    Co(II) changes its coordination number from tetrahedral to octahedral           
  • b)
    Co(II) changes its oxidation state to Co(III)           
  • c)
    Tetrahedral crystal field splitting is not equal to octahedral crystal field splitting           
  • d)
    Co(II) forms kinetically labile while Co(III) forms kinetically inert complexes
Correct answer is option 'A'. Can you explain this answer?

Silica gel does not contain [CoCl4]2-. Silica gel is a porous form of silicon dioxide (SiO2) that is commonly used as a desiccant or drying agent. It does not typically contain any metal complexes like [CoCl4]2-.
