Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex

Renewable energy resources can possibly provide effective sustainable energy solutions. However‚ the application of solar energy for power generation purposes is not currently competitive with conventional fossil fuel systems. A recent academic study compared the solar aided power generation (SAPG) solution with that of a similar-sized stand-alone concentrating solar power (CSP) plant in the South African context. The objective was to determine the real advantages of these technologies‚ if any
