What Would Be the Concentration of Hydronium Ions in a Solution

question 96

Multiple Choice

What would be the concentration of hydronium ions in a solution that had a pH = -3? Why would such a solution be impossible to prepare?

• A)Concentration of \(\mathrm { H } _ { 3 }\) \(\mathrm { O } ^ { + }\) = 3 M.It is impossible because it is hard to measure such a small amount of hydronium ions accurately.
• B)Concentration of \(\mathrm { H } _ { 3 }\) \(\mathrm { O } ^ { + }\) = 30 M.It is impossible because pH can not be negative.
• C)Concentration of \(\mathrm { H } _ { 3 }\) \(\mathrm { O } ^ { + }\) = \(10 ^ { 30 }\) M.It is impossible because any container used to hold the acid would immediately corrode.
• D)Concentration of \(\mathrm { H } _ { 3 }\) \(\mathrm { O } ^ { + }\) = \(10 ^ { 3 }\)
