Complexometric Determination Of Water Hardness By Angelica Aquino CHM 152 LL January 5‚ 2013 METHODS: 1. Prepare an approximate 0.004 M disodium EDTA solution. To prepare this solution‚ weigh about 0.7-0.8 g of Na2EDTA and dissolve in 500 mL deionized water in your plastic bottle. Make to to shake the bottle to dissolve the salt. 2. Obtain a 250-mL Erlenmeyer flask and transfer a 10 mL of CaCO3 using a buret into the flask. 3. Measure 30 mL of deionized water and add it into the titration

DENITRIFICATION OF CONTAMINATED WATER INTRODUCTION:- This is an eco-friendly and economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria

Water is an odorless‚ colorless‚ tasteless chemical compound that makes up well more than half of the human body. In addition to being prominent in the make-up of the human body‚ it also covers all but approximately 30% of the Earth’s surface‚ and can be found naturally in all three states of matter: liquid‚ solid and gas. Water is a covalent bond known most commonly by its empirical form; H2O. It can also be identified by the Lewis Dot Structural form shown in the figure in the upper right corner
