Lab Determination of the solubility product of Ca(OH)2.pdf - Name Group members Determination of the Solubility Product of Calcium Hydroxide, Determination of the Solubility Product of Calcium Hydroxide, The goal of our lab was to approximate the Ksp of calcium hydroxide. Solubility Product for Calcium Hydroxide Accepted value for the Ksp of calcium hydroxide: 6.5 x 10^-6 I am having trouble with the Data Analysis questions at the bottom. Comments. We did this by observing the reaction between calcium nitrate and sodium hydroxide, with one of the solutions … Share. In one trial, the concentration of calcium nitrate was, halved consecutively while the concentration of sodium hydroxide remained the same. This preview shows page 1 - 2 out of 2 pages. Solids and liquids are not contained in the expression. Solubility Product for Calcium Hydroxide GOAL AND OVERVIEW A saturated solution of Ca(OH) 2 will be made by reacting calcium metal with water, then ltering o the solids. This lime is solid but dissolves slightly into aqueous calcium and hydroxide ions, a solution known as limewater. 1 can be combined with Eqn. Lab 10 - Solubility Product for Calcium Hydroxide Goal and Overview A saturated solution of Ca(OH) 2 will be made by reacting calcium metal with water, then filtering off the solids. The purpose of this lab is to discover the dissolved concentration of hydroxide in a saturated solution of Ca(OH)2. Solids are not contained in the expression because they are pure substances and do not, The Ksp is equal to the concentration of the dissolved ions raised to the power of their, coefficients in the balanced equation.

Solubility Product Lab Report Answers Online Library Solubility Product Lab Report Answers Solubility Product Lab Report Answers Wikibooks is a useful resource if you’re curious about a subject, but you couldn’t reference it in academic work. General Chemistry 3 Lab (CH 233 Lab) Academic year. Ca(OH)2, commonly known as lime, is a weak base that when in solution will not completely disassociate. Course. 114 Exp 9 S11 URI Department of Chemistry. Last Update: Ocober 13, 2013 . Determining the Ksp of Calcium Hydroxide Lab Report a) Purpose: To calculate the Ksp of Ca(OH)2 by determining the [OH-] for a saturated Ca(OH)2 solutions by titration with a standard HCl solution. Record your data down below and determine the Ksp of Ca(OH). SOLUBILITY PRODUCT CONSTANTS The solubility product constant K sp is a useful parameter for calculating the aqueous solubility of sparingly soluble compounds under various conditions. An equilibrium constant, K, is related to ΔG for a process through Eqn. In the, next trial, the concentration of sodium hydroxide was halved and the concentration of calcium, nitrate was held constant. Introduction.
