GRAVIMETRIC ANALYSIS Methods in GA Precipitation Method - involves isolation of an ion in solution by a precipitation reaction‚ filtering‚ washing the precipitate free of contaminants‚ conversion of the precipitate to a product of known composition‚ and finally weighing the precipitate and determining its mass by difference. From the mass and known composition of the precipitate‚ the amount of the original ion can be determined. Volatilization Method -the analyte or its decomposition products

Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.

Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325
