1) Let’s write the reaction equation:
CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl
The exchange reaction proceeds to the end, as a precipitate of Cu (OH) 2 is precipitated, salts: CuCl2 and NaCl
2) Let’s write the reaction equation:
6 КOH + Fe2 (SO4) 3 = 3 К2SO4 + 2Fe (OH) 3
The exchange reaction proceeds to the end, as a precipitate of Fe (OH) 3 is precipitated, salts: Fe2 (SO4) 3 and K2SO4
3) Let’s write the reaction equation:
2LiOH + Pb (NO3) 2 = 2 Li NO3 + Pb (OH) 2
The exchange reaction proceeds to the end, as a precipitate of Pb (OH) 2 is precipitated, salts: Pb (NO3) 2 and Li NO3
4) Let’s write the reaction equation:
K2CO3 + 2HCl = 2KCl + CO2 + H2O
The exchange reaction proceeds to the end, as CO2 gas is released, salts: K2CO3 and KCl
5) Let’s write the reaction equation:
Na2CO3 + H2SO4 = Na2SO4 + CO2 + H2O
The exchange reaction proceeds to the end, as CO2 gas is released, salts: Na2CO3 and Na2SO4
6) Let’s write the reaction equation:
Na2S + 2 HCl = 2NaCl + H2S
The exchange reaction proceeds to the end, as H2S gas, Na2S and NaCl salts are released
7) Let’s write the reaction equation:
CaCl2 + Na2CO3 = 2NaCl + Ca CO3
The exchange reaction proceeds to the end, as a precipitate of Ca CO3 is released, salts: CaCl2, Na2CO3, NaCl, Ca CO3
8) Let’s write the reaction equation:
2AgNO3 + CaCl2 = 2AgCl + Ca (NO3) 2
The exchange reaction proceeds to the end, as a precipitate of AgCl is precipitated, salts: AgNO3, CaCl2, AgCl, Ca (NO3) 2
