Part of the lab the temperature of the solution was changed the remaining amount of the non filtered calcium hydroxide was heated to 70 degrees celsius with a bunsen burner. Determination of the solubility product constant of calcium hydroxide essay sample the equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant  , ksp of the solute. By measuring the concentration of the hydroxide ion, [oh-], the concentration of calcium ion, [ca 2+], can be calculated and the k sp value for ca(oh) 2 at 25 o c obtained. K sp of calcium hydroxide 1 author: j m mccormick last update: ocober 13, 2013 introduction an equilibrium constant, k, is related to δg for a process through eqn 1 and as long as δh and δs are independent of temperature, eqn 1 can be combined with eqn 2 to determine δh and δs from the temperature dependence of k.

Solid) is called precipitation reaction the reactants are soluble, but the product formed would be insoluble and hydroxide -oh -1 iodate io 3 --1 iodide i --1 name formula charge nitrate no 3 --1 nitride n 3--3 oxalate c 2 o 4 confer your observations with your lab partner and work together to write the required chemical equations. Determining ksp of calcium hydroxide introduction aqueous calcium hydroxide, also known as lime water is used to verify the presence of carbon dioxide gas, (carbon dioxide reacts with the calcium hydroxide to produce calcium carbonate) this is achieved by bubbling the gas through the solution, if the solution turns cloudy then the. Calcium hydroxide dissolving in water yields calcium ion and 2 hydroxide ions, thus the ksp would be: ksp = (ca)(oh)^2 to make the calcium hydroxide we just add water skip to content shikhar's lab reports.
