Gravimetric determination of chloride biology essay
Gravimetric analysis is a type of quantitative analysis method that measures the mass of a substance to determine its concentration or purity. In the case of a chloride salt, a method is described for the determination of trace metals in silver chloride by means of atomic absorption spectroscopy. Solid silver chloride is dissolved in ammonia solution and impurities are extracted. Name: Tiare Cuellar Lab: Title: Gravimetric Analysis of a Chloride Salt Objective: To illustrate typical techniques used in gravimetric analysis by quantitatively determining the amount of chloride in an unknown. Materials: 1. Digital. 4 Bunsen burner. Funnels 2 5.The Mohr method for the determination of chloride in water is an advanced pH method. It should be carried out between pH. 5-9.0. It is better to perform between pH -8. At a higher pH value, the silver ions react with hydroxide ions and precipitate as silver hydroxide.
