Abstract Gravimetric analysis describes the methods for finding the chemical constituent of analyte in a solution through analytical chemistry. This method uses the mass of solid SO42-‚ with an unknown quantity and quality‚ to qualitatively determine the makeup of the solid SO3-. Two separate experiments with the initial compounds of BaCl2 and SO42- were put into solution to allow for the BaSO4 precipitate to form. Through filtration and ignition of precipitate containing ashless papers

lubricates moving metal parts that would otherwise grind together. As you drive‚ the oil pump circulates oil within your engine and the oil filter catches the deposits that build up over time. The oil filter performs its own type of car maintenance by keeping the oil clean. But as the oil gets older‚ the number of deposits in the oil continues to build and the filter is unable to extract all of the material. When this happens‚ the color of the oil changes and it indicates the oil should be changed.

carbonate from aqueous solutions of calcium chloride and sodium carbonate. These solutions will be prepared from 2.01 g of calcium chloride and 1.06 g of sodium carbonate . Materials: 3 beakers 100 mL graduated cylinder rubber policeman funnel filter paper Procedure: 1. Put on your safety goggles. 2. Obtain two clean beakers. Rinse the inside of the beakers with a small amount of distilled water. 3. Obtain the correct amounts of calcium chloride and sodium carbonate. Enter these masses

Decantation. This separates a liquid from an insoluble solid by carefully pouring the liquid from the solid without disturbing the solid. 4. Filtration. This separates a solid from a liquid through the use of a porous material as a filter. Paper is a good filter. Filters allow the liquid to‚ pass through but not the solid. 5. Evaporation. This is the process of heating a mixture in order to drive off a volatile liquid and make the remaining component dry. The mixture that will be separated in

implementation. 4. Provide C++ software overview. 2 What is a Kalman Filter and What Can It Do? A Kalman filter is an optimal estimator - ie infers parameters of interest from indirect‚ inaccurate and uncertain observations. It is recursive so that new measurements can be processed as they arrive. (cf batch processing where all data must be present). Optimal in what sense? If all noise is Gaussian‚ the Kalman filter minimises the mean square error of the estimated parameters. 3 What

------------------------------------------------- Treatment of industrial wastewater The various types of contamination of wastewater require a variety of strategies to remove the contamination Brine treatment Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist‚ industrial brine treatment may contain unique combinations of dissolved ions‚ such as hardness ions or other metals‚ necessitating specific

Pour the contents of the beaker into the funnel. 9. After there is no more liquid in the funnel‚ take the filter paper and lay it somewhere to air dry. 10. When the contents are completely dry‚ weigh it. 11. Subtract the original weight of the filter paper. The remaining weight will be your actual yield
