Ca oh 2 ksp value
WebThe Ksp for this reaction will be: Ksp = [Ca2+ (aq)][OH- (aq)]2 Remember that the solid state is not included in a Ksp expression. Every substance that forms a saturated solution will have a Ksp. However, for very soluble substances like NaCl, the value is so large that the concept is rarely used. WebThe solid you will be working with in this lab is Ca (OH)2. Write the equilibrium equation for the dissociation of solid Ca (OH)2 in water. Ca (OH)2 <=> Ca2+ + 2OH-. 2. Write the expression for the Ksp of this …
