Unexposed silver halides are removed from photographic film when they react with sodium thiosulfate (Na2S2O3, called hypo) to form the complex ion Ag(S2O3)23-. The reaction with silver bromide is: AgBr(s) + 2 S2O32- (aq) ⇌ Ag(S2O3)23- (aq) + Br- (aq) The equilibria that need to be considered are: Ag+ + 2 S2O32- (aq) ⇌ Ag(S2O3)23- (aq) Kf = 4.7 x 1013 AgBr(s) ⇌ Ag+ (aq) + Br- (aq) Ksp = 5.0 x 10-13 What mass of Na2S2O3 is required to...

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
