3. Write the steps in deducing the chemical formulae of the followingcompounds.Sodium sulphate, potassium nitrate,ferric phosphate, calcium Oxidealuminium hydroxide |
|
Answer» Hey dear,● ANSWERS -Chemical formula is deduced on the basis of CATION & anion in the compound.1) Sodium sulphate CONTAINS Na+ cation & (SO4)2- anion, thus molecular formula of sodium sulphate is Na2SO4.2) Potassium nitrate contains K+ cation & (NO3)- anion, thus molecular formula of potassium nitrate is KNO3.3) Ferric phosphate contains Fe2+ cation & (PO4)2- anion, thus molecular formula of ferrous phosphate is FePO4.4) Calcium oxide contains Ca2+ cation & O2 anion, thus molecular formula of calcium oxide is CaO.5) Aluminium hydroxide contains AL3+ cation & OH- anion, thus molecular formula of aluminum hydroxide is Al(OH)3. |
