Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula ca() 2it is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. Determining the ksp of calcium hydroxide calcium hydroxide is an ionic solid that is sparingly soluble in water a saturated, aqueous, solution of ca(oh)2 is represented in equation form as shown below. Determining the ksp of calcium hydroxide by titration of saturated ca(oh)2(aq) with hcl(aq) abstract: titration is a technique that has been used in this experiment to identify the ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. The first one asks to calculate the [oh-] from these results, and the second asks to find the [ca2+] from these results we initially used 15ml of the filtered saturated calcium hydroxide, and then used 0050 m hcl to titrate it.
Determination of the ksp of ca(oh)2 and the ksp of ca(oh)2 in va determination of the molecular weight of a gas determination of the solubility of a solid in a liquid sodium hydroxide. Determination of the solubility product constant of calcium hydroxide abstract this experiment aimed to determine the solubility product constant (ksp) of ca(oh)2 as well as to evaluate the effects of common and non-common ions on its solubility. A saturated solution of calcium hydroxide (lime water) is titrated with hydrochloric acid of known concentration, and the ksp of calcium hydroxide is determined from the resulting information safety calcium hydroxide is caustic and hydrochloric acid is corrosive both can cause blindness. 3 to find a ksp value, you really need to know the concentration of one ion for example, if you know that in solution the [oh-] = 80 x 10-6, what does the [ca2+] have to be.
Chem229 jialu determination of the ksp of calcium hydroxide abstract: the goal for this experiment was to determine the ksp of calcium hydroxide using three different methods gravimetric analysis, using the ph of the solution, and titration. For calcium hydroxide is 65 × 10 -6, so calculate a rough value of the concentration of oh - ion, [oh -], in the saturated solution (see prelab question on webassign to two significant figures. Purpose: to determine the solubility product (ksp) of calcium hydroxide (aqueous) introduction: ksp is how much a salt dissociates, so a greater ksp would mean more dissociation. Determination of the solubility product constant of calcium hydroxide jra ibale institute of chemistry, college of science university of the philippines, quezon city, philippines date performed: january 30, 2013 instructor's name: maro r peña.
Calcium hydroxide is an ionic solid that is sparingly soluble in water a saturated, aqueous, solution of ca(oh) 2 is represented in equation form as shown below the solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and. Calculate the solubility product of calcium hydroxide when a titration is done answer questions what volume is occupied by 0779 mol of co2 at 2886 k and 911 mmhg. 6 calcium hydroxide titration obtain about 5 ml ca(oh) 2 solution in a beaker use a pipet to withdraw 100 ml of this solution and place it in an erlenmeyer. Determining the ksp of calcium hydroxide objectives titrate a saturated aqueous ca(oh)2 solution with a standard hcl(aq) solution determine the [ohi and [ca i for the saturated solution.
World-class support for science & math determining the k sp of calcium hydroxide pre lab questions-580368 1 determine the k sp of calcium fluoride (caf 2 ), given a molar solubility of 458 x 10 5 mol/l. Determining the ksp of calcium hydroxide lab adv comp 23 from advanced chemistry with vernier, vernier software & technology, 2004 introduction calcium hydroxide is an ionic solid that is sparingly soluble in water. The purpose of the study was to experimentally determine the solubility product (ksp) of aqueous calcium hydroxide using its saturation concentration of hydroxide and acid-base titrations with hydrochloric acid.
Solubility product constants compound formula k. Calcium hydroxide + hydrochloric acid - balanced molecular equation, complete and net ionic equation - duration: 4:34 the organic chemistry tutor 21,150 views.
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. Diverse-ion effect common-ion effect in this experiment, the solubility product simultaneous equilibria constant, ksp, of calcium hydroxide, ca(oh)2, was obtained using titration the the common-ion effect is an application of equilibrium reaction of ca(oh)2 can be the le chatelier's principle. Computer 23 advanced chemistry with vernier 23 - 1 determining the ksp of calcium hydroxide calcium hydroxide is an ionic solid that is sparingly soluble in water. From the volume of saturated calcium hydroxide used, you will be able to determine its concentration and thus its ksp value (note that this is the reverse of a normal titration procedure usually, the solution of known concentration in the buret is added to the unknown solution in the erlenmeyer flask.
