Answer:
This discussion on 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 octahedralb)Co(II) changes its oxidation state to Co(III)c)Tetrahedral crystal field splitting is not equal to octahedral crystal field splittingd)Co(II) forms kinetically labile while Co(III) forms kinetically inert complexesCorrect answer is option 'A'.
