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

Making Water Turbines Most Energy Efficient How does a wind turbine’s output vary with wind pressure (height of water)‚ the flow rate‚ size of the motor‚ and type of blade? Introduction There are many types of energy used today: Fossil fuels‚ coal‚ nuclear energy‚ solar energy‚ geothermal energy‚ hydrogen energy‚ hydroelectric energy‚ wind energy‚ and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled‚ unlike wind energy
