KSP, pH and precipitation related issues related to manganese hydroxide
I have encountered similar problems before, and I finally understand it; see if I can give you some reference. You can verify such an idea; one is completely settlement and the other is to start generating.After the pH value of the KSP corresponds to the pH value is completely reached, there is no manganese ion in the solution.When the pH value of the beginning is reached, there is only a precipitation generation. I do n’t understand the manganese ion; the nickel ion concentration I encounter is 1.5mol/L, and the pH5-6 starts to generate nickel hydroxide. When it is completely settle, the pH is greater than 9.

According to the theory, 2mol/L manganese sulfate solution, adjusting the pH value, should only occur at about 7.48, please help the big guys to answer
