lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette and burette. Then we had to perform three measurement

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at

Complexometric Determination of Water Hardness Kayla Partridge Britni Gonzales 09/15/2014 Abstract Determining the water hardness of unknown sample #55 was determined by complexometric titration. With the use of disodium salt EDTA as the solution to chelate the metal impurities and the Eriochrome Black T indicator as the solution used to help visualize when the impurities were completely chelated‚ along with a few other solutions to help the reaction. Unknown water sample #55 experimental

the iron rivets used for the construction of the Titanic were cheaply made and resulted in the damage from the iceberg to be more extensive than normal. The problem of the iron rivets were the way they were created. The usual composition for iron rivets would use about two percent of a substance called slag (Spignesi 265). “Slag is glass residue that is left over from smelting metallic ores” (Spignesi 265) It is used in iron rivets to make them structurally stronger
