WebDec 6, 2013 · As one oxygen is not wholely solely with one silicon atom but it is bonded with two silicon atoms thus contribution of one oxygen is 1/2 towards one SiO2 molecule.. As … WebSilicon dioxide is soluble in hot aqueous base; thus, strong bases destroy the passivation. Removal of the passivation layer allows the base to dissolve the silicon, forming hydrogen gas and silicate anions. For example: Si(s)+4OH−(aq) → SiO44−(aq)+2H2(g) Si ( s) + 4OH − ( a q) → SiO 4 4 − ( a q) + 2H 2 ( g)
