This chemistry video tutorial explains how to calculate ksp from molar solubility. Embed an image that will launch the simulation when clicked. These comparisons can only be ; made for salts having the same ; IONION ratio. If you can remember the 6 strong acids you'll know that all other acids are weak: HCl HBr HI H_2SO_4 HClO_4 HNO_3 Exercise 18.2. When the Qsp and Ksp have equal values, then the solution has become saturated. 2. Supports offline use and offers improved performance. Relate the charges on ions to the number of ions in the formula of a salt. Ag2S Ksp 1.0 X 10-49 Ni(CN)2 Ksp 3.0 X 10-23 Ag2S ? 1. For example let's take the compound Barium Carbonate BaCO 3 (this is … Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. The Qsp is also called the ion product because it is the product of concentrations of ionic species at any moment (not at a specific moment such as saturation). Ksp = [Pb 2+][CrO 4 2-] Using the dilution equation, C 1 V 1 = C 2 V 2, determine the initial concentration of each species once mixed (before any reaction takes place). We've partnered with Leaning Technologies to allow our Java sims to run in a browser. Qsp is the product of concentrations of ionic species in an unsaturated, saturated or a supersaturated solution.

The liquid portion of that system has the soluble solutes. 2 Ag S-2 Ni(CN)2 ? The solubility product is determined when the solution is saturated with that substance. 4. The solubility product constant is given for a solution that is saturated with a substance. If there are any other salts for which you know the value of the constant, please let us know and we will update the table. Below are the values of the Ksp product constant for the most common salts. In a saturated solution that is in contact with solid Mg (OH) 2, the concentration of Mg 2+ is 3.7 × 10 –5 M. Qsp is the solubility product quotient of a solution. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Calculate Ksp values. Filed Under: Inorganic Chemistry Tagged With: Ksp, Ksp and Qsp Differences, Ksp and Qsp Similarities, Ksp Definition, Ksp Nature, Ksp Solution State, Ksp vs Qsp, Qsp, Qsp Definition, Qsp Nature, Qsp Solution State. Qsp is the solubility product quotient of a solution. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. Overview of sim controls, model simplifications, and insights into student thinking These slightly soluble salts dissolve until K. spis satisfied. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. The closer the K_a value is to one the stronger it is (the term "strong acid" means that it completely disassociates). Therefore, Ksp (the solubility product constant) is a special form of Qsp. Summary. The key difference between Ksp and Qsp is that  Ksp indicates the solubility of a substance whereas Qsp indicates the current state of a solution. 5. If the Qsp is higher than the value of Ksp, a precipitate is formed. Difference Between Density and Concentration, Difference Between Complexing Agent and Chelating Agent, Difference Between Iodine and Resublimed Iodine, Difference Between Intermolecular and Intramolecular Hydrogen Bonding, Side by Side Comparison – Ksp vs Qsp in Tabular Form, Difference Between Coronavirus and Cold Symptoms, Difference Between Coronavirus and Influenza, Difference Between Coronavirus and Covid 19, Difference Between Andhra and Telangana in India, Difference Between Monounsaturated and Polyunsaturated Fats, Difference Between Interstitial and Appositional Growth, Difference Between Methylacetylene and Acetylene, Difference Between Nicotinamide and Nicotinamide Riboside, Difference Between Bleaching Action of SO2 and Cl2, Difference Between Collagen Elastin and Reticular Fibers. Side by Side Comparison – Ksp vs Qsp in Tabular Form 6. The difference between Ksp and Qsp is that Ksp is the solubility product constant whereas Qsp is the solubility product … (A saturated solution is when there is a state of equilibrium between the dissolved, dissociated, undissolved solid, and the ionic compound). Ksp is the solubility product constant and Qsp is the solubility product quotient. How do PhET simulations fit in my middle school program? A common ion means one of the ionic species that are already present in that solution. Solubility Product Constant (K sp) Values at 25 o C. Salt: K sp: Salt: K sp: The K sp values found in this table are nominal values for use in my General Chemistry courses and do not necessarily represent the best-kown values of the solubility product constants. Ksp is the solubility product constant of a particular substance. If the Qsp value is less than the Ksp for a substance in a solution, more solids can be dissolved in that solution. Whenever you do it though, please give us the source. Overview and Key Difference Ksp and Qsp are very related terms in chemistry. We hope they will prove usefull to you. 24 Comparing Solubilities Which salt is more soluble? Compare the Difference Between Similar Terms. All rights reserved. Determine the ratio of anions and cations that create a neutral compound. 1. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } The PhET website does not support your browser. However, what if you do not know which way the reaction will progress? A simple relationship between \(K_c\) and the reaction quotient, known as \(Q_c\), can help.
