Q. Study the reaction scheme below and then answer the following:
a) Give the chemical formula of (i) Marble (ii) Gas A (iii) Solid B
b) Solution C is normally called ______, when Gas A is bubbled through Solution C, a white precipitate of _________ is formed.
c) On bubbling excess of Gas A through the white precipitate in "b", the white precipitate dissolves form____
Dear student,
(a)
1. Marble is in general terms metamorphosed limestone, mostly composed of recrystallised carbonate minerals. So the bulk of marble is just CaCO3.
2. Gas A is carbondi oxide
3. Solid B is calcium hydrooxide
(b) quicklime, It is calcium carbonate, CaCO3, a white insoluble compound
(c) calcium bicarbonate
Regards
