Question

Equation for Le Chateliers Experiment

1. Na2CO3 + AgNO3

2. Add drops of 6M HNO3

3. Add drops of 0.1M HCl + NH3 concentrated

4. Again add drops of 6M HNO3

5.Add some more drops of NH3 conc.

6.Add drops of 0.1M KI

7.Add drops of Na2S

Answer 1

Na2CO3 +2 AgNO3 ----> 2NaNO3 + Ag2CO3

2. Add drops of 6M HNO3

NO3 - concentration increases at both sides equilibrium no change

3.Add drops of 0.1M HCl + NH3 concentrated

Cl-ions gives from HCl but concentration of Ag+ ions decreases on both sides equilibrium no change

4. Again add drops of 6M HNO3

NO3 - concentration increases at both sides equilibrium no change

5. Add drops of 0.1M KI

I-ions gives from I but concentration of Ag+ ions decreases on both sides equilibrium no change\

6. Add drops of Na2S

Na+ concentration increases at both sides equilibrium no change
