Hydrochloric acid does not react with salt solution 1) silver nitrate 2) potassium nitrate 3) sodium silicate 4) lead nitrate. Write equations for those substances with which hydrochloric acid reacts.
1) HCl + AgNO3 = AgCl ↓ + HNO3
2) does not respond
3) 2HCl + Na2SiO3 = 2NaCl + H2SiO3 ↓
4) Pb (NO3) 2 + 2HCl = PbCl2 ↓ + 2HNO3
With potassium nitrate, the exchange reaction will not proceed, so there are no binding ions to precipitate, or a weakly dissociating substance (for example, water) is formed
