Zinc hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Zn(OH)2 <---> Zn2+ + 2 OH- b. its possible to dissolve significant amounts of Zn(OH)2 in solutions in which the concentration of either Zn2+ or OH- is very very small. explain using Ksp c. explain why Zn(OH) might have very appreciable solubility in 1M HCl.
