Let us take the oxidation no. of Si in the given compound is x. So [ 2.1 + x + 6.(-1)] = 0. Solving it we get x =+4.

Nice simple solution. I wonder what is the oxidation state of Chromium(Cr) in K 3 C r O 8 K_3 Cr O_8 , and the oxidation state of sulfur(S) in H 2 S 2 O 8 H_2 S_2 O_8 ! Can you help me out?

You can figure out the O.S. of Cr and S in K3CrO8 and H2S2O8 respectively by drawing their Lewis structures.
