    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

    Na+ H+ Wallert and Provost Lab Excel with hard work and inquiry Ammonium Sulfate PPT Protocol Theory and Introduction: Ammonium Sulfate Precipitation is a classic first step to fractionate proteins by causing perturbations in the solvent with respect to ionic strength. Historically‚ separation methods were limited and as a result precipitation methods were highly used with very fine cuts in ppt conditions. As more choices of inexpensive and quality resins are commercially available precipitation

    The video that I observed was an adult that was given a modified barium swallow (MBS). The adult was given thin liquids to complete the MBS. The MBS observes all stages of swallowing. The oral preparatory stage of swallowing was not clearly observed in the video. However‚ the oral transport‚ pharyngeal‚ and esophageal stages of swallowing were observed. During the oral transport stage‚ the tongue forms a groove that pushes the bolus posteriorly. However‚ it was observed that the patient’s tongue

    Quantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50 times more soluble at 100°C

    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
