浓度为0.1mol/L的下列几种溶液:NaHSO4,Na2CO3,NaHCO3,CH3COONa,CH3COOH,NH4Cl ,pH由小到大顺序浓度为0.1mol/L的下列几种溶液:Na2CO3,NaHCO3,NaOH,NaNO3,CH3COOH,NaHSO4,NH4Cl ,pH由小到大顺序怎么判断的?

问题描述:

浓度为0.1mol/L的下列几种溶液:NaHSO4,Na2CO3,NaHCO3,CH3COONa,CH3COOH,NH4Cl ,pH由小到大顺序
浓度为0.1mol/L的下列几种溶液:Na2CO3,NaHCO3,NaOH,NaNO3,CH3COOH,NaHSO4,NH4Cl ,pH由小到大顺序
怎么判断的?

酸溶液的pH小于强酸弱碱盐,强酸弱碱盐pH小于中性溶液,中性溶液小于强碱弱酸盐溶液,强碱弱酸盐溶液小于碱溶液.所以
NaHSO4(相当于强酸)
