As we learned in concept

Stoichiometry -

Stoichiometry deals with measurements of reactants and products in a chemical reaction.

- wherein

aA (g) + bB (g) → cC (g) + dD (g)

Here, ‘a’ moles of A(g) reacts with ‘b’ moles of B(g) to give ‘c’ mole of C(g) and ‘d’ moles of D(g)

 

 The number of Cl atoms not in the cordinate comples are free to precipitate as Agcl.

Co forms a complex with 6 ligands with NH3 molecules with priority are Cl here

Similarly CoCl_{3}.5NH_{3}  2Cl will precipitate

CoCl3 .4HN3  1Cl will precipitate
