Question
Silica (SiO2) is an impurity that must be removed from a
metal oxide or sulfide ore when the ore is being reduced to
elemental metal. To do this, lime (CaO) is added. It reacts
with the silica to form a slag of calcium silicate (CaSiO3),
which can be separated and removed from the ore.
(a) Write the balanced equation for this process.
(b) Can this be considered a Lewis acid–base reaction? If
so, what is the Lewis acid and what is the Lewis base?
