177. In complex MCl3·5H2O, the secondary valency of metal is 6 and it has no molecule of water present out of coordination sphere. Calculate the volume of 0.1 M AgNO3 solution needed to precipitate the free chloride ions in 200 ml of 0.01 M solution of the complex (1) 80 ml (2) 40 ml (3) 20 ml (4) 120 ml

Step 1
The complex has a secondary valency of 6, which means the metal ion is coordinated to 6 ligands. Since there are no water molecules outside the coordination sphere, all 5 water molecules are coordinated to the metal. Show more…

EConcentrated hydrochloric acid solution is $37.0 \% \mathrm{HC}$ and has a density of $1.19 \mathrm{~g} / \mathrm{mL}$. A dilute solution of $\mathrm{HCl}$ is prepared by diluting $4.50 \mathrm{~mL}$ of this concentrated $\mathrm{HCl}$ solution to $100.00 \mathrm{~mL}$ with water. Then $10.0 \mathrm{~mL}$ of this dilute $\mathrm{HCl}$ solution reacts with an $\mathrm{AgNO}_{3}$ solution according to the following reaction: $$ \mathrm{HCl}(\mathrm{aq})+\mathrm{AgNO}_{3}(\mathrm{aq}) \longrightarrow \mathrm{HNO}_{3}(\mathrm{aq})+\mathrm{AgCl}(\mathrm{s}) $$ How many milliliters of $0.1105 \mathrm{M} \mathrm{AgNO}_{3}$ solution is reauired to precipitate all of the chloride as $\mathrm{AgCl}(\mathrm{s})$ ?
Calculate the approximate volume (in mL) of 0.1 M silver nitrate (AgNO3) that will be needed to precipitate the chloride from a 0.1156 g chloride salt sample that is 55% weight chloride using the following equations: mol Cl- in salt sample = (Mass of Chloride salt (in g) x 0.55) / Molecular weight of chlorine (in g mol) Vol of AgNO3 required = (mol Cl- (aq) in salt sample / Concentration of AgNO3) + 5 mL

One way to determine the amount of chloride ion in a water sample is to titrate the sample with standard $\mathrm{AgNO}_{3}$ solution to produce solid AgCl. $$\mathrm{Ag}^{+}(a q)+\mathrm{Cl}^{-}(a q) \rightarrow \mathrm{AgCl}(s)$$ If a 25.0 -mL water sample requires $27.2 \mathrm{mL}$ of $0.104 M \mathrm{AgNO}_{3}$ in such a titration, what is the concentration of $\mathrm{Cl}^{-}$ in the sample?
