experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. 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 the titration and stockpot‚ use

Water Pollution Water – The Elixir of Life Can you imagine life without water? Take a minute and think about it. We need water for all our daily essential activities – drinking‚ bathing‚ cleaning… In fact‚ every living thing on this planet needs water Water pollution And what do we do with this vital resource? We take its all important ability – we all know that water can dissolve many of the thing that we dump in it – to make it a giant rubbish bin. In fact‚ we even throw things

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

Purpose: The purpose of this lab was to determine the freezing point of pure water‚ the experimental van’t Hoff factor for a substance and the molar mass of an unknown solution. Reagents: 25mL deionized Water ¼ to ½ inches of rock salt 25mL Sodium Nitrate (NaNO3 ) 25mL unknown solution – handle unknown solution carefully Procedure: For part 1‚ the freezing point of deionized water was determined. An ice bath was prepared by filling a 600mL beaker ¾ full of ice and covered with ¼ to

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The
Premium Chemistry Volume Density
Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

First of all his stepfather‚ Hunter Jordan had died from a stroke which was very hard on him because of how close he was to Hunter even though he was not his biological father. Also around this age of 14‚ James was going through an identity crises because of the difference in skin color to his mother. James was
