Experiment # 4a Title: Determination of the Hardness of Water from a Waterfall Aim: To determine the molarity of EDTA and to determine the hardness of water by measuring the concentrations of calcium and magnesium in a water sample by titration. Abstract: The aim of this experiment was to determine the molarity of a sample of EDTA and then to use this sample to determine the hardness of a sample of water. This was done using a titrimetric method. This was standardized using calcium chloride.

Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble

Influence of Heat Treatment on Hardness and Corrosion Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties

Florence due to the fluorescent mineral impurities or due to locality. Chemical composition is another method because minerals have a fixed chemical composition it is easy to test mineral with this method. And hardness minerals are identified by their hardness based on the Mohs scale of mineral hardness based on their ability to scratch any mineral with a number lower than theirs and their inability to scratch any mineral with a number higher than theirs. A mineral is naturally occurring crystalline solid
