Effect of Salt on the Boiling Point of Water" Lab Question: How does adding salt to water affects it’s boiling point? Prediction : In this paper‚ a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system Materials : 200 mL of distilled water‚ 2 beakers‚ 5grams of salt‚ beaker

Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer the questions below.

BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the
