Clicker Questions pH scale
1)
B is the answer because pure water can be clear
like solution A in this example and it is neutral.
2)
D More than one (B and C) is the answer because
solution B and C are above a pH of 7 which indicates that they are basic.
3)
C is the answer because it has many more
hydronium ions than hydroxide ions which mean it is much more acidic.
4)
B is the correct answer because the
concentration of hydroxide ions is higher than hydronium.
5)
D More than one (A and B) is the answer because
both samples A and B have more hydronium ions within their solutions than
hydroxide.
6)
A is the correct answer because adding water
will dilute the concentration of the acid causing the pH to be more dilute.
7)
B is the answer because when adding more water
the ions of the basic solution will become more dilute causing the
concentration to be dilute and the pH to decrease.
8)
A is the correct answer because the lower the pH
the more acidic the solution is and the higher the pH is the more basic the
solution is.
9)
E is the correct answer because the hydronium to
hydroxide ratio is the value that one most observe.
10) A
is the correct answer because if extra hydroxide ions are added to the solution
then the solution will attempt to reach equilibrium by shifting to the left.
