Q. The equation that is incorrect is :

1. $({\Lambda }_m^0{)}_{NaBr}-({\Lambda }_m^0{)}_{NaCl}=({\Lambda }_m^0{)}_{KBr}-({\Lambda }_m^0{)}_{KCl}$
2. $({\Lambda }_m^0{)}_{NaBr}-({\Lambda }_m^0{)}_{NaI}=({\Lambda }_m^0{)}_{KBr}-({\Lambda }_m^0{)}_{NaBr}$
3. $({\Lambda }_m^0{)}_{H_{2}O}=({\Lambda }_m^0{)}_{HCl}+({\Lambda }_m^0{)}_{NaOH}-({\Lambda }_m^0{)}_{NaCl}$
4. $({\Lambda }_m^0{)}_{KCl}-({\Lambda }_m^0{)}_{NaCl}=({\Lambda }_m^0{)}_{KBr}-({\Lambda }_m^0{)}_{NaBr}$
