K. sp. Looks like you’ve clipped this slide to already. K_sp is a constant that is the solubility product and it is a constant so that is not changing. Solubility product constant, Ksp: the equilibrium constant expression for the dissolving of a slightly soluble solid. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. In such an equilibrium, Le Chatelier's principle can be used to explain most of the main factors that affect solubility. Looks like you’ve clipped this slide to already. Complete the statement. Ksp = [Ca 2+ ] [SO 42-] Ksp is the solubility product constant and the right hand side of this equation is often called the ion product. Assignment Hence the temperature at which a solubility product is measured should always be stated. A substance’s solubility product (K sp) is the ratio of concentrations at equilibrium.Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated. Solubility Product (Ksp) = [products]x/ [reactants]y but..... reactants are in solid form, so Ksp= [products]x Ksp= [A3+]2 [B2–]3 i.e. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

If you mix together two solutions containing barium ions and sulphate ions and the product of the concentrations would exceed the solubility product, you get a precipitate formed. Email:avitsureshindia@gmail.com. A The balanced equilibrium equation is given in the following table. Calculate the solubility product. Dr.S.SURESH Calculation of solubility: If we know the solubility product of a meagerly soluble salt like AgCl we can calculate the solubility of the salt and vice versa. It will give them practice taking and interpreting information from graphs and applying them to strengthen their arguments. Solubility Products 1. This product will challenge your student's understanding of solubility curves. The Solubility Product Constant • When an excess of a slightly soluble ionic compound is mixed with water, an equilibrium is established between the solid and the ions in the saturated solution and represented by a constant that is temp dependent. 6/17/2003 OFB Chapter 9 19 Precipitation and the Solubility Product Precipitation from Solution Exercise 9-4: The K sp of thallium (I) iodate is 3.1 ×10-6 at 25oC. Calculate the solubility product. Solubility Product (Ksp) = [products]x/[reactants]y but..... reactants are in solid form, so Ksp=[products]x i.e. Ppt Formation Condition(Solubility Product Ksp) By Arvind arora.

See our Privacy Policy and User Agreement for details. It is expressed in a complex unit—grams of solute per 100 ml of solvent at a given temperature. Hence, the term solubility can be defined as a property of a substance (solute) to dissolve in a given solvent. (Solubility and solubility product) Presentation Summary : Chapter 17: SOLUBILITY: K sp. Ksp and factors affecting solubility are included as well as solved problems. Precipitation from Solution: Does a solid ppt form? When Qsp is greater than Ksp for a solution, a precipitate is likely to form. Solubility and Solubility Products. The concept of solubility product is very useful in explaining many phenomenons. Enough solid is produced to reduce the concentrations of the barium and sulphate ions down to a value which the solubility product allows.

Molar solubility, solubility, and solubility product all refer to what type of solution? Solution. Salt Type. If we let x equal the solubility of Ca 3 (PO 4) 2 in moles per liter, then the change in [Ca 2 +] is once again +3x, and the change in [PO 4 3−] is +2x. = s s = s2= 3.9105 3.9105= 1.52109. In the study of solubility equilibrium we generally deal with low solubility compounds (those which dissolve poorly) • Low solubility compounds are … Now customize the name of a clipboard to store your clips. And so now we can solve for Ksp because we know the equilibrium Case II: When , then solution is saturated in which no more solute can be dissolved but no ppt. Various fields in which it can be used are:- 1. Solubility product In general, solubility product, Ksp, is the mathematical product of its dissolved ion concentrations raised to the power of their stoichiometric coefficients.

SOLUBILITY EQUILIBRIUM • Solubility refers to the ability of a substance to dissolve. If you add a common ion to this solution it will always decrease the solubility of the salt. –The equilibrium constant for this process is called the solubility product constant, K sp. Qsp, the ion product, is the products of concentrations of ions in a ratio of products to reactants whereas Ksp, the solubility constant, describes the same ratio at equilibrium conditions. We can insert these values into the ICE table. See our User Agreement and Privacy Policy. The solubility product of a salt is usually obtained from its solubility.
