How to determine the pH of a metal salt solution when the metal ions do not undergo hydrolysis?
Thread Content
As the title suggests, taking trivalent iron ions as an example, their nitrates undergo a high degree of hydrolysis in aqueous solution. I want to determine the minimum pH value of the solution required to ensure that all iron is present in the form of trivalent ions Can the specific pH value be calculated? Can it be detected through specific testing methods?
It can be calculated; pH 2.5
What is the basis or process for the calculation? Are there any reference materials? Thank you!
