Once the sample was analyzed and all three peaks of the elements were found. A one point calibration curve was made from the results of the instructor’s standard by plotting peak area against concentration‚ which was lastly used to determine the concentration of each

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. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

Abstract: During the lab a better agent for absorbing Procion Red Dye was trying to be found. Using the different dilutions of a stock solution and a spectrophotometer an Absorbance vs. Concentration graph was created and using the trendline from that graph it was determined which agent‚ zeolite‚ magnetic zeolite‚ or charcoal were better at absorbing the dye. From the results collected it was found that charcoal was the best at absorbing the dye‚ when moles of dye per gram of agent used were calculated
