Question

Write the empirical formula for at least four ionic compounds that could be formed from the following ions:

Pb+4

,

NH+4

,

IO−3

,

CO−23

Answer 1

Ang Empirical formula of a chemical compound is - the simplest positive integar ratio of atoms present in a compound Here we have two cations - - Poth = Lead in NHU = Ammonium ion: to help - Two anions- I 0,= Iodaté ion CO32- Carbonate ion

- First we take pilt with IОg and CO2- (9) Psht x IO3 1. 3 Pb (103) 7 lead iodate =) This is the empirical formula because it & the simplest ratio of atoms present in lead iodaté (6) Pilt Costa 2 Pь, Co, 5, - lead carbonate Empirical formula - Pb (CO3)₂ simplest ratio of lead and carbonate - Now take Nhyt with IOğ and coz (C) NH4 I 05 • Nhy I 0,5 Ammonium iodate - This is the empirical formula.

d) Nhyt C03² NHO CO3 → Ammonium carbonate - This is the simplest ratio of atoms in ammonium carbonate. So, it is the empirical formula
