In a saturated solution of calcium phosphate

WebIn a saturated solution the solid is in equilibrium with its ions e.g : CaCO3(s) ⇌ Ca2+ (aq) + CO2− 3(aq) The expression for Ksp is: Ksp = [Ca2+ (aq)][CO2− 3(aq)] We don't include the concentration of the solid as this is assumed constant. So if we know the concentration of the ions you can get Ksp at that particular temperature. WebThe solution is saturated and at equilibrium. Q > Ksp. The solution is supersaturated, and ionic solid will precipitate. Figure 17.1 The Relationship between Q and Ksp If Q is less than Ksp, the solution is unsaturated and more solid will dissolve until the system reaches equilibrium ( Q = Ksp ).

Webplaque contains much higher concentrations of calcium and phosphate than does saliva,4 and its critical pH may be as low as 5.1. Thus, the critical pH is not a constant, because the levels of calcium and phosphate in plaque fluid vary among indi-viduals. The more calcium and phosphate that are present in a solution, the lower its critical pH. WebVideo transcript. - [Instructor] Changing the pH of a solution can affect the solubility of a slightly soluble salt. For example, if we took some solid lead two fluoride, which is a white solid, and we put it in some distilled water, the solid is going to reach an equilibrium with the ions in solution. WebApr 15, 2024 · The solubility of calcium phosphates is also depend on C a / P (Ref.2). For example, both monocalcium phosphate ( C a ( H X 2 P O X 4) X 2) and monocalcium phosphate monohydrate ( C a ( H X 2 P O X 4) X 2 ⋅ H X 2 O) are highly soluble in water at 25 ∘ C ( C a / P is 0.5). stuart williams ice
