... the result accuracy of two decimal places can be obtained. It is a simple, reliable, and economical experiment that is simple to use. Reactions between aqueous solutions are generally fast. The endpoint is when the indicator suddenly changes colour, this means the reaction is complete. At the endpoint you stop the ... HCL used 0.0209 mol 0.0209 mol 0.0209 mol Concentration of HCL 1.045 mol/L 1.045 mol/L 1.045 mol/L 2. Obtain about 120 mL of hydrochloric acid solution in a 250 mL beaker. Label the beaker. Rinse a buret with about 10 mL of the sloution, and let the liquid drain through the...

... gas will escape and cause the analytical results to be low. None the less if this photochemical decomposition happens in the presence of excess Silver ions in an aqueous solution the following additional reaction occurs: 3Cl2(g) + 3H20(l) + 5Ag+(aq) ï‚® 5AgCl(s) + CIO3-(aq) + 6H+(aq) If the above ... the quantity of the precipitate; generating a systematic error in the analysis, this is because there is a probability of presence of anions in the solution which will cause the analytical results to be overstated as they will form along with the Silver chloride salt and will be collecte...
