Describe the solubility of al(oh3 with respect to ph.

The solubility of Al(OH)3 with respect to pH is soluble at low pH, insoluble in pH-neutral solution, and soluble at high pH. We can express it as this:
Solubility equilibrium expression for Al(OH)3 is 
Al(OH)3 <==> Al3+(aq) + 3OH-(aq) 
Initial 0 1.0x10^-3 M 
change +s +3s 
Remember that solubility is used in chemistry to describe the properties of a solid compound that is mixed with and fully dissolves in a fluid without leaving any undissolved particles.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
