Introduction: calcium hydroxide is a soft white caustic powder used in making mortar, cements, calcium salts, paints, and petrochemicals it is also used in saltwater aquaria to make up kalkwasser/limewater solutions for reef tanks, and is used as a. Page i-41 / determination of k sp, ∆g˚, ∆h˚ and ∆s˚ for ca(oh) 2 lab determination of k sp, dg˚, dh˚ and ds˚ for ca(oh) 2 the solubility of hydroxides is easily determined through a titration with a suitable acid (such as hcl.

This reaction shows that solid calcium is mixed with water this reaction creates ca(oh)2 which makes an equillibrium reaction with ca2+ and 2oh- the equillibrium reaction is: ca(oh)2(s) → –ca2+(aq) + 2 oh (aq) the equillibrium constant for the reaction is: ksp = [ca2+][oh ]2 procedure: 1 gather all requires materials. Use the determination of the ksp of ca(oh)2 chemistry laboratory kit to help students understand the relationship between the equilibrium constant and solubility this microscale lab is easy to set up and quick to perform. From the balanced reaction equation the number of moles of ca(oh)2 is half of the number of moles of hcl reacted, so 319510^{-4} / 2 = 1597510^{-4} mol. I have to calculate the ksp value for calcium hydroxide from experimental data we titrated 1000 ml of saturated ca(oh)2 aqueous solution with 1100 ml of 001607 m edta i got the # of moles of edta by multiplying molarity by liters = 00001768 mol since the stoichiometric ratio of ca^2+ to edta.

Ksp of ca oh 2

ksp of ca oh 2 Without a pure solution (of ca(oh)2) the amount of the solution would change that was needed to titrate the hcl the value of solution went up thus giving a different value then was first assumed for ksp the less that was filtered lead to a higher value for the ksp then first thought.
