亚硝酸  化学式HNO2。亚硝酸仅存在于稀的水溶液中,是一种弱酸,不稳定,易分解成NO2和NO,也能发生如下歧化反应:  3HNO2─→HNO3+2NO+H2O    在亚硝酸中氮原子的氧化数是+3,是一种中间氧化态,因此,亚硝酸既具有氧化性,又具有还原性,而氧化性比还原性更为突出。例如,它在水溶液中能将I-离子氧化为单质碘:  2HNO2+2I-+2H+─→I2+2NO+2H2O这个反应可用于分析测定。在多数的情况下,亚硝酸可还原成氧化氮NO,也可还原成氧化二氮N2O、氮、胲NH2OH或氨NH3。它被氧化时,即成为硝酸。    将二氧化氮和氧化氮的混合物溶解在接近零度的水中,即生成亚硝酸的水溶液:  NO2+NO+H2O─→2HNO2在亚硝酸盐溶液中加入酸,也可得到亚硝酸的溶液:  NaNO2+HCl─→HNO2+NaCl亚硝酸在工业上用于有机合成,使胺类转变成重氮化合物,从而制备偶氮染料。
