CaF2+H2SO4 gives HF. HF reacts with SiO2 to give SiF4. On hydrolysis it gives H4SiO4. Answer should be c
One doubt, how you know the order of the reaction like
Why can't CaF2 or H2SO4 directly can react with SiO2?
Do we have to remember these facts or there is some methodology behind?
You do have to remember some things dude, this is inorganic after all
Yes there is! This CaF2 is actually the lab preparation of HF! The further reaction with SiO2 is a very very well known reaction. It is corrosion of glass. It is used in etching of glass. These reaction are the most important reactions of HF. That is why i remember them.
@Supreeta_Sen there is always some way to remember them. Random reactions are usually not asked unless specifically mentioned.
In my book , the hydrolysis reaction is forming option d
Don't know buddy, it was taught to us in class that H4SiO4 f
