Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al‚ 2013). Determining the mass of calcium by using gravimetric analysis was the objective of the experiment. A 25 mL

temperature difference between the objects. Heat is measured in a calorimeter and the units for heat are joules or calories. The calorimeter uses the Law of Conservation of Energy which states that energy is never created or destroyed but is transferred between objects. Temperature is a measure of the average kinetic energy of the particles an object which is different that the heat which is all the energy in the object. Temperature can be used to calculate heat by looking at the change in temperature

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

use of pGlo plasmids. II Materials and Procedures The first procedure of the lab was to obtain two microtubes and label one +pGlo and the other –pGlo with a marker. Next‚ the tubes were placed in the microtube rack and 250 μl of CaCl2 was transferred into each tube using a sterile pipette. After placing the microtubes in ice‚ a sterile inoculation loop was used to pick up a single colony of bacteria from the E. coli starter plate. Next‚ the +pGlo microtube was removed from the ice and‚ to ensure
