Cu + 4HNO3 = Cu(NO3)2 + 2NO2 + 2H2O 3Cu + 8HNO3 = 3Cu(NO3)2 + 2NO + 4H2O
NO2/NO中只含1个N原子,即:
NO2 NO HNO3
1.12L /22.4 = 0.05mol 0.05mol HNO3
1.92g Cu = 1.92/64 = 0.03mol,生成Cu(NO3)2用去0.06mol HNO3
NaOH + HNO3 = NaNO3 + H2O
1mol/LNaOH 10ml = 1* 0.01= 0.01mol HNO3
硝酸总浓度 = (0.05 + 0.06 + 0.01)mol /0.01L = 12 mol/L
