+
-
3) A solution of an acid contains more H than OH ions
4) A solution of an acid turns litmus blue
7. Which statement describes characteristics of an Arrhenius base?
1) It changes blue litmus to red and has a pH less than 7
2) It changes blue litmus to red and has a pH greater than 7
3) It changes red litmus to blue and has a pH less than 7
4) It changes red litmus to blue and has a pH greater than 7
8. When a solution of an acid is tested with a pH paper, the result will be a pH
1) Above 7, and the solution will conduct electricity
2) Above 7, and the solution will not conduct electricity
3) Below 7, and the solution will conduct electricity
4) Below 7, and the solution will not conduct electricity
