1. If I have a saturated KHP solution and add NaOH, what will happen to the solubility and the Ksp?
2. If I have a saturated KHP solution and add HCL, what will happen to the solubility and the Ksp?
Okay, I know that KHP is amphoteric so
1. KHP + NaOH = H2O + P2- and I am guessing equilibrium goes to the right and solubility increases. right?
2. KHP + HCL = H2P +KCL ? and I am guessing eq goes to the right and solubility increases? but I also found out that H2P is less soluble than KHP, so now I am not sure if the solubility of KHP decreases or increases.
I am thinking that since the Ksp are constants, they don't change, and what is changing is the solubility. right?
