- PH of cation salt is greater than 7 because HCl + NH3 ----- NH4+ + Cl-. Can someone show me how the same rule is true for Mg(OH)2? (This is not on the list of strong base that Chad gave me, so I guess it is a weak base.)
- For question 110, Cu, Ag, Ag can be salts of weak base. How come they don't undergoes acid-base reactions that can affect the PH?
- What are some common charges we should know for the chemistry section? I have encountered problems that you have to know the charge of the ions (Example: Qs 42 from destroyer)
