Assignment:
What is the minimum pH at which aluminum hydroxide, Al(OH)3 will precipitate from a 0.020 M Al(NO3)3 solution. Consider activity effects.
The Ksp for Al(OH)3 is 3x10^(-34).
Assume the pH can be changed without increasing the solution volume.
Provide complete and step by step solution for the question and show calculations and use formulas.
