Question

which one of the following precipitation reactions does not occur?

Question 16 Which ONE of the following precipitation reactions does NOT occur? O Pb(NO3)2 + 2NaCl → 2NaNO3 + PbCl2 O Pb(NO3)2 + ZnSO4 → PbSO4 + Zn(NO3)2 KNO3 + MgSO4 Mg(NO3)2 + K2SO4 CaCl2 + Na2CO3 – CaCO3 + 2Naci O Pb(NO3)2 + ZnSO4 – PbSO4 + Zn(NO3)2

Answer 1

You have already marked a correct option.

Those reaction in which formation of precipitate or I insoluble solid take place is called precipitation reaction. In these 5 reaction ,4 are precipitati and reaction.. formation of insoluble solid like Pbc₂, Pb soy, CaCO, here indicate precipitation reaction, The only reaction which is not precipitation reaction is this : KNO2 + Mg 50 u Mg(NO3), + K, Soy. Mellaroel and Kasoy are not insoluble solid so it is not a precipitation reaction. Third option is correct option
