A comparison of our sketch to the exact titration curve (Figure 9.44f) shows that they are in close agreement.įigure 9.44 Illustrations showing the steps in sketching an approximate titration curve for the titration of 50.0 mL of 0.0500 M NaCl with 0.100 M AgNO 3: (a) locating the equivalence point volume (b) plotting two points before the equivalence point (c) plotting two points after the equivalence point (d) preliminary approximation of titration curve using straight-lines (e) final approximation of titration curve using a smooth curve (f) comparison of approximate titration curve (solid black line) and exact titration curve (dashed red line). Finally, we complete our sketch by drawing a smooth curve that connects the three straight-line segments (Figure 9.44e). Next, we draw a straight line through each pair of points, extending them through the vertical line representing the equivalence point’s volume (Figure 9.44d). The blue line shows the complete titration curve. The red points corresponds to the data in Table 9.18. Table 9.18: Titration of 50.0 mL of 0.0500 M NaCl with 0.100 M AgNO 3 Volume of AgNO 3 (mL)įigure 9.43 Titration curve for the titration of 50.0 mL of 0.0500 M NaCl with 0.100 M AgNO 3. Additional results for the titration curve are shown in Table 9.18 and Figure 9.43. As silver chloride, silver bromide and silver iodide are precipitates.\].Silver nitrate is a colourless solution.AgCl is soluble in water and it is a colourless solution. ![]() All silver compounds are insoluble in water.What are the correct statements of followings about silver? Therefore, AgCl is not soluble in nitric acid Silver chloride does not react with nitric acid. That means bond between silver cation and chloride ion is strong. Silver chloride (AgCl) is not soluble and there is very less silver and chloride ions in the aqueous phase.ĪgCl is also not soluble in water, because the forces favouring formation of silver hydroxide (AgOH) are too weak to break the ionic bonds between silver and chlorine in AgCl. Silver bromide and silver iodide are precipitates and very useful in identification of halide ions inĪlso they have colors when they form precipitates.Ĭolors of silver halides Silver halide name Chemical formula Color Silver chloride AgCl white Silver bromide AgBr light yellow / pale yellow Silver iodide AgI YellowĪgCl is not soluble in alcohols but soluble in alkali cyanide solutions. Silver chloride's solibility is in micro grams scale (very small). Solubility of NaCl is 36 g/100 ml of water at 50 0C.Solubility of AgCl is 520 µg/100 ml of water at 50 0C.If you want to get proved AgCl is insoluble in water, compare its solubility and NaCl's solubility in water. Why and how do you say AgCl is not soluble in water Note that, AgCl is not soluble in dilute acids. When excess concentrated HCl is added to AgCl precipitate, precipitate dissolve and give colourless solution.ĪgCl dissolves in alkali cyanide solutions This + is a colourless solution.īut when solution is acidified, again AgCl precipitate forms. In this section, we are going to find out, in which solutions AgCl will be dissolved?ĪgCl is soluble in aqueous ammonia solution and give Cl coordination complex compound. NaCl (aq) + AgNO 3(aq) → AgCl (s) + NaNO 3(aq)ĪgNO 3 is a soluble aqueous colourless solution. Also sodium nitrate (NaNO 3) is given as the other salt. When AgNO 3 is mixed with aqueous NaCl solution, AgCl white precipitate is deposited at the bottom of theĪqueous solution. ![]()
