Title: Determination of 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

that had been used to make the structures. Marble and limestone used to be very common materials for art that was meant to be exposed outdoors. To a surprise‚ the acid rain could turn the calcium carbonate molecules that were found on these stone materials into calcium sulphate molecules. This is the result of calcium sulphate being dissolved by water; acid rain would eventually wash away the outside layer of buildings and statues. There are many examples all across the world of the corrosive effects

grinding mill which is widely used in the calcium carbonate grinding process. Firstly‚ the calcium carbonate ore be put into the primary crushing equipment jaw crusher to crush‚ then to the secondary crusher to get the size which is suitable to grinding in the T130X superfine grinding mill‚ after these crushing and grinding processes‚ we can get the suitable size finished production or the calcium carbonate powder. We also provide the whole calcium carbonate grinding production line machines‚ jaw crusher

Acid Rain Research Paper What is acid rain? Rain is one of the most dire and essential needs for a thriving ecosystem‚ and to sustain human‚ animal‚ and plant life. The water provided by the water cycle‚ the event causing rain‚ is required to keep all life on Earth alive. Rain‚ although naturally acidic‚ seems to have been increasing at a rapid rate due to many reasons. Some of these many reasons include‚ pollution. Pollution from homes‚ factories‚ power stations‚ cars‚ and many more
