-in the saturated solution of Sr(IO 3)2 Calculation of K sp Once you have determined the concentration of one of the ions in the saturated solution you can use the mole ratio of the ions in the solid to find the concentration of all other ions making up the solid In your experiment solid Sr(IO 3)2 breaks up into 2 moles of IO 3
Filter the saturated Ca(OH)2solution through a piece of filter paper in a funnel into a 100 mL beaker 6 Using a 10 mL graduated cylinder measure out 5 00 mL of the filtered solution with a plastic pipet Pour the 5 0 mL of solution into a clean 125 mL Erlenmeyer
saturated salt solution to the vapor pressure of the water is the activity (or relative humidity) of the saturated salt solution (5) Measurement with a calibrated humidity sensor A chamber containing a saturated salt solution and a humidity sensor are brought to equilibrium at a controlled temperature
(A saturated solution is when there is a state of equilibrium between the dissolved dissociated undissolved solid and the ionic compound) For example let's take the compound Barium Carbonate BaCO3 (this is an ionic compound that is not very soluble) BaCO3(s) Ba2+ (aq)+CO32- (aq) First we can write down the equilibrium constant expression:
1) The curve shows the # of grams of solute in a saturated solution containing 100 mL or 100 g of water at a certain temperature 2) Any amount of solute below the line indicates the solution is unsaturated at a certain temperature 3) Any amount of solute above the line in which all of the solute has dissolved shows the
Solutions can be saturated unsaturated or supersaturated A saturated solution contains the maximum amount of solute that can dissolve The amount of solute needed to make a saturated solution depends on the identity of the solute the solvent and the temperature of the solution An unsaturated solution can dissolve more solute
