pH=0的c(H+)=pH=1的c(H+)= pH=6的c(H+)=pH=2的c(H+)= pH=7的c(H+)=pH= pH=0的c(H+)= pH=1的c(H+)= pH=6的c(H+)= pH=2的c(H+)= pH=7的c(H+)= pH=3的c(H+)= pH=8的c(H+)= pH=4的c(H+)= pH=9的c(H+)= pH=5的c(H+)= pH=10的c(H+)= pH=11的c(H+)= pH=12的c(H+)= pH=13的c(H+)= pH=14的c(H+)= pH=15的c(H+)= pH=16的c(H+)= pH=17 的c(H+)= pH=18的c(H+)= pH=0.2的c(H+)= pH=0.3的c(H+)= 群群宝贝1年前2: 啊哈尔滨共回答了17个问题 | 采纳率100%

pH=lg[H+]那么[H+]=10^(-pH),代入计算即可.数字后面单位都是mol/L
pH=1的c(H+)=0.1 pH=6的c(H+)=10^-6
pH=2的c(H+)=0.01 pH=7的c(H+)=10^-7
pH=3的c(H+)=0.001 pH=8的c(H+)=10^-8
pH=4的c(H+)=10^-4 pH=9的c(H+)=10^-9
pH=5的c(H+)=10^-5 pH=10的c(H+)=10^-10
pH=11的c(H+)=10^-11 pH=12的c(H+)=10^-12
pH=13的c(H+)=10^-13 pH=14的c(H+)=10^-14 此时c(OH-)=1
pH=15的c(H+)=10^-15 此时c(OH-)=10 pH=16的c(H+)=10^-16 c(OH-)=100,没见过那么大的浓度.更别说pH=17,18了
pH=17 的c(H+)=10^-17 pH=18的c(H+)=10^-18
pH=0.2的c(H+)=10^-0.2 pH=0.3的c(H+)=10^-0.3
