Question

Will AgCl dissociate at a higher degree (be more soluble) in 0.05M KNO₃ or in 0.05M Ca(NO₃)₂? Explain why and show your math.

Answer 1

Tonic strength of a solution is represented as 1 2 3 ? ciz a 2 concentration of ith in Ziz.charge of ith in Hence, ionic strength of 0.05m KNO3 : solution. I knog 2 & (Cat. 21 h + CNOZ 2008) of 10.08 x 14005.2012) R 0.05 Ionic strength of 0.65M Ca(NO3)2 solution. sca (203)2 = lalt +2N03 7 0.005 2x0.05 -0.1 I [capovos)} a { (ceczy zonas + Covog zamos) ad (0.05x2? + 0.1 x 12). 2 = 0.15 The effect of ionic strength of a solution on the reaction rate represented as

tog (l/ko) a 1:02.2 2. Ik This oppression indicates that with increasing the ionic strength of a solution the rate of reaction increases.

Since I ['caenog),] ) I (KNP3] Неми, Апати в поrа tъм и in Ca(NO3)2 than . KNO3 solution.
