Please answer the following data with solution. Activity No. 8Determination of Chloride Ion Concentration by GravimetryGravimetric analysis is a method in quantitative analysis where an unknown sample is dissolvedin an appropriate solvent, and the analyte is converted to an insoluble form or precipitation of a knowncompound and then weighing the precipitate. In order to do a gravimetric analysis, a cation must be foundthat forms an insoluble compound with chloride. Ions such as Ag+, Pb²+, and Hg₂²+ form insoluble chlorides.Therefore, silver chloride (AgCl) could be used to determine % Chloride (CI), because it is insoluble and itcan be formed pure and is easily filtered.Ag+ (aq) + Cl(aq) →→ AgCl(s)One of the most useful applications of gravimetric analysis is the determination of chloride innatural waters such as seawater and water in rivers and lakes. In this experiment the chlorine content ofan unknown soluble chloride salt is to be determined. The unknown is dissolved in distilled water anddilute silver nitrate solution is added to precipitate out the chloride as AgCl.NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)Note that all of the aqueous species in the above reaction exists as ions in solution:NaCl(aq) exists as Na+ and ClAgNO3 exists as Ag* and NO3NaNO3(aq) exists as Na+ and NO3AgCl(s) is a white solidProcedure Link: https://www.youtube.com/watch?v=dERZhN-01f8 DataUnknown Number: 345Trial 2Trial 3Mass unknown, g0.10150.1205Mass crucible, g20.195519.1986Mass crucible + precipitate, g20.524619.4873Mass precipitate, g0.32910.2887Mass chloride, g% Chloride in unknownAverage % Chloride:Standard deviation:Show Calculations for Trial 1:a.

00 mL of a diprotic acid primary standard solution was accurately prepared to a concentration of 0.1431 M. Three samples of this primary standard solution were used as samples in a titration to standardize an aqueous solution of sodium hydroxide, NaOH, which would be used as a titrant. Using the following table of data for the titration of the primary standard acid with NaOH, calculate the average concentration of NaOH.
