Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including

Willy Rupprecht Date(s) performed: October 2 - 3‚ 2012 Gravimetric Analysis of an Unknown Group 1 Metal Carbonate Purpose: The purpose of this lab is to determine the identity of a Group 1 metal carbonate compound by gravimetric analysis. Procedure: The unknown carbonate is weighed and then dissolved in water. A solution of CaCl2 (calcium chloride) is added to the metal carbonate solution to precipitate the carbonate ions as CaCO3 (calcium carbonate). The precipitate is then filtered‚ dried

Gravimetric Analysis of CA2+ as CaC2O4.H2O Introduction Weight determination represents one of the most accurate and precise form of measurement carried out in lab analysis. Thus‚ gravimetric analysis provides a great assay of a variety of analytes. Mixtures of compounds in difference phases provide us with one of the simplest methods of separation and mass explorations. Separating a solid mass from a liquid involves the commonplace

Determination In “The Glass Castle” we see many different possibilities pertaining to Maslow’s Hierarchy of Needs. We see the father‚ Rex and one of the daughters‚ Maureen‚ who fall victim to Maslow. Then there’s Jeanette and the mother‚ Rose Mary who have both seemed to achieve self-actualization regardless of their hardships. Traditionally‚ Maslow’s Hierarchy is thought to be achieved by working up from the bottom of the pyramid to get to the top. However‚ in “The Glass Castle” this is not particularly

This experiment contains three separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g

Zinc Tris-thiourea Sulfate (ZTS) is a Semi Organic Nonlinear Optical (NLO) material which finds applications in the area of laser technology‚ optical communication‚ data storage technology‚ and optical computing etc. The author has successfully grown ZTS crystal by gel method. Gel technique has been adopted at ambient temperature to attain better result. The grown crystals were transparent and colourless. The crystal size has been obtained the range about 5mm X 3mm X 2mm.
