Given be One Lthe island A with pH = 7 and One Lthe island B with pH = 8. Assessments (That 's right – wrong) the following: Statements:

1. a) The H₃O⁺-Konzentration of A is 10 times This is it. Large How The The Lthe island B
2. b) The H₃O⁺-Konzentration of A is Right now. The OH^– Concentration of A
3. c) The H₃O⁺-Konzentration of B is 10 times small as The c(OH^–) The Lthe island B

Lösung:

1. a) correctly
       pH = 7 → c(H₃O⁺) = 10^-7 mol/l;
       pH = 8 → c(H₃O⁺) = 10^-8 mol/l
2. b) correctly
       In special cases In the case of pH=7, c(H₃O⁺) = c(OH^–)
3. c) wrong.
       pH=8 → c(H₃O⁺) = 10^-8 mol/l;
       pOH = 14-pH = 6 → c(OH^–) = 10^-6 mol/l
       So what do you mean? is c(H₃O⁺) 100· I 'll take it . small as c(OH^–)
