Desalination of sea water by pH control


NaCl + HCl >NaCl(s)

MgSO4 + NH4OH > Mg(OH) + NH4SO4

MgSO4 + CaCl2 > CaSO4 + MgCl2

NaOH + MgCl2 > Mg(OH)2 + NaCl

NH4SO4 + NaOH > Na2SO4 + NH3

Na2SO4 + CaCl2 > CaSO4 + NaCl

NaCl + HCl > NaCl(s)

NH4Cl + NaOH > NaCl + NH3

Removal of Hydrochloric acid by heat a absorbant or reduced pressure

Here is a list of reactions
Based off sodium chloride being insouble in hydrochloric acid

As you can see it only when sodium chloride is increased
Then it becomes insouble in HCl acid
So the goal is to increase sodium chloride concentration
Then percipitate with HCl
