1). A solution containing hcl would likely have
Ans: a low pH and a high pOH.
2). The ph of a solution decreases by 2.0. how does the hydronium ion concentration of the
solution change?
Ans: increases to 100 times the original concentration
3). Which describes an alkaline solution?
Ans: acidic (NOT CORRECT)
4). Which of these correctly defines the ph of a solution?
Ans: the negative log of the hydronium ion concentration
5). What is the ph of a solution with [h+] = 1.25 mc015-1.jpg 10-10 m?
use mc015-2.jpg.
Ans: 9.90
6). Which statement best describes the ph of pure water?
Ans: It is neutral because the concentration of hydronium ions equals that of hydroxide
ions.
7). How can the ph of a solution be calculated if the poh is known?
Ans: by subtracting the pOH from 14
8). What is the equilibrium constant of pure water at 25°c?
Ans: 10-14
