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 H3O+ = 3 M. It is impossible because it is hard to measure such a small amount of hydronium ions accurately. B) Concentration of H3O+ = 30 M. It is impossible because pH cannot be negative. C) Concentration of H3O+ = 1030 M. It is impossible because any container used to hold the acid would immediately corrode. D) Concentration of H3O+ = 103 M. It is impossible because only so much acid can dissolve in water before the solution becomes saturated.
