SOLUBILITY PROBLEMS. Here are some practice problems for writing K sp expressions. Write the chemical equation showing how the substance dissociates and write the K sp expression: ... Note the solubility is very much reduced in 0.100 M Na2SO 4 because of the common ion effect.
This example problem demonstrates how to determine the solubility product of an ionic solid in water from a substance's solubility.
Solubility Product (Ksp) Precipitation Helpful Hints.... Write the balanced ionic equation for the reaction. ... Problem 4 The molar solubility of PbCl 2 in 0.10 M NaCl is 1.7 x 10-3 moles in a liter (that is 1.7 x 10-3 moles of PbCl 2 will dissolve in 1 liter of the solution).
Practice: Solubility equilibria questions. ... Common polyatomic ions. Dissolution and precipitation. Introduction to solubility and solubility product constant. Solubility from the solubility product constant. Solubility and the common-ion effect. ... this problem won't count towards your progress! Try your best to work it out first.
Problem : Place the following in order of decreasing solubility in ammonia: CH 2 Cl 2, CH 4, H 2 O . Ammonia is a polar solvent that can form hydrogen bonds. Water, has exactly the same characteristics so it is the most soluble in ammonia.

The key to solving solubility problems is to properly set up your dissociation reactions and define solubility. Solubility is the amount of reagent that will be consumed to saturate the solution or reach equilibrium of the dissociation reaction. AgCl The dissociation reaction of AgCl in water is AgCl (s) ↔ Ag + (aq) + Cl-(aq) For this reaction, each mole of AgCl that dissolves produces 1 ...
The molar solubility of a substance is the number of moles that dissolve per liter of solution. For very soluble substances (like sodium nitrate, NaNO 3), this value can be quite high, exceeding 10.0 moles per liter of solution in some cases.. For insoluble substances like silver bromide (AgBr), the molar solubility can be quite small.
Practice Problems: Solubility Rules 18. Base your answers to the following questions on the information below. Many consumer products are packaged in containers made of a plastic called polypropylene. Polypropylene is a polymer made from a biproduct of oil and widely used because it is inexpensive, durable, insoluble in water and non-toxic.
Confused about molarity? Don't be! Here, we'll do practice problems with molarity, calculating the moles and liters to find the molar concentration. We'll also have to use conversion factors to ...
