Barium Nitrite Formula


How to do It

Barium nitrite have the right to be ready by decomposing silver- nitrite through barium chloride <4>.

2AgNO2 + BaCl2 = 2AgCl + Ba(NO2)2


It can also be made by pouring a heat solution of barium nitrate over lead and also boiling the mixture because that 1.5 to 2 hours <7>.

Ba(NO3)2 + 2Pb = Ba(NO2)2 + 2PbO
