Question

• When solutions of silver nitrate and sodium chromate are mixed, solid silver chromate forms (Ag_CrOx) forms. Write the molecular, total ionic, and net ionic equations for this reaction.

Answer 1

Ans 3. In acid-base reaction, an acid react with base to form salt and there is no change of oxidation state of any atom.

Ans 1) Molecular Reaction, 2Ag No 3 Cag) + NaCroular) +2 Na Nozlar Ag Crouss I Згоum - had precipitate Total ionic equation 2Ag + 2 N0gt at 2 Na + crou Ag Grou (sdh + 2Na +2N0,0 To change it into net ionic, remove the spectator ions Cie No Nat) So, the met ionic Aqn > 2Ag & Crou? Ag Croy(s) I brown-red @ zully. 502 Precipitate Ois of Zn =+2 Ois of s=+6 ois of ce =-1 Ois of each o=-2 ③ Nitric acid (HNO₃) @ dichromate ion (69 20 2 ) ois of Hati, os of o=ng Ois of N=+5 het Ois of cren ois of each o=ag. so axn+7(-2) = -2 20-14=22 x=+6 so oes of r=476

Eg:- HCl + NaOH → NaCl + H2O

Here the oxidation state of H is +1 on both the sides . Similarly for other atoms the oxidation state of atoms in products are same as that in reactants...On the other hand in redox reaction ,transfer and withdrawal of electrons takes place.So there is a change of oxidation state on the product side...

Eg:- H2 + F2 → 2 HF

Here O.S of H is 0 in reactant side but +1 in product side...similarly F has O.S of 0 in reactant side and -1 in product side ...

So the main different in the products of redox reactions and acid base reaction is that in redox reaction the oxidation state changes but in acid base reaction it remains same as that of reactant...
