chloride by the Mohr Method Objective: To determine chloride by using Mohr Method. Introduction: The Mohr method is the method used to determine the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added‚ a precipitate of silver chloride forms. Ag+ + Cl- AgCl(s) (Ksp for AgCl is 1.810-10) The chloride ion (Cl-) is an important anion found in solids and solutions. Chloride is the predominant anion of sea water with a molarity

Elizabeth Au (1) Serena Chan (3) Sharon Chan (4) Christy Chan (5) BIOLOGY LAB REPORT Investigation of the effect of metal ions on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive

Railroads had a monopoly on shipping which raised costs and affected profit‚ the value of crops deflated‚ and big business was a strong opponent to the much needed ’Free Silver Movement’ that farmers were relying on. The first major topic regarding farmers discontent with their economic situation involves the shipping monopolies controlled by the railroad companies. The cost of transportation was spiraling out of control
