Answer:
Solution with a pH = 1
Explanation:
So the pH equation is pH = -log[H+]. To get the [H+] (hydrogen ion concentration), you rearrange to get [H+] = 10^-pH.
Solution with a pH = 1
, [H+] = .1 M
Solution with a pH = 12
, [H+] = 1*10^-12 M
Solution with a pH = 7
, [H+] = 1*10^-7 M
Solution with a pH = 9
, [H+] = 1*10^-9 M
Solution with a pH = 5, [H+] = 1*10^-5 M
Another way to get the answer: a high hydrogen ion concentration means that the solution should be more acidic. The most acidic pH of the 5 solutions is the one with a pH = 1.
The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.
Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
