13、答案:C
解析:若Va>Vb,醋酸过量,根据物料守恒可知,n(CH3COOH)+ n(CH3COO-)=0.05Va,n(K+)= 0.05VVb,则A选项正确;若Va=Vb,反应后为CH3COOK溶液,由于的CH3COO-水解而显碱性,根据质子守恒可知,B选项正确;若Va<Vb,说明碱过量,当碱液加的量足够多,则可以存在c(K+)>c(CH3COO-),C选项错误;D选项符合电荷守恒,正确。
12、答案:B
[解析]标准状况下,水是液体,A项错。由碳酸根离子水解的离子方程式可知,水解引起阴离子数目增多,B项正确。C项没有指明条件,22.4L并不一定是1mol,但该混合气体的质量为28g是正确的,故C错误。1分子NH3中含3个N-H共价键,3.4g氨气中含N-H数目为0.6NA ,D项错。
