I enjoyed doing the virtual lab. I treat water as an occupation so I understood how and what to add to treat the water. If you have a low (acidic) pH then you should add sodium hydroxide. If you have total coliforms‚ you should chlorinate before and after treatment. Often‚ we test houses for total coliforms and e. coli. If the bacteria is positive‚ then we chlorinate the well. After we make sure all the chlorine is throughout the house‚ we let it sit for 24 hours to disinfect the pipes and

Bohnenberger Professor Van Doorn ENVS 150-002 2 March 2015 Water Quality Lab Report Introduction: When people are asked about how water is characterized‚ they usually will think of saltwater‚ freshwater‚ safe-to-drink freshwater‚ and tap water. Only a few people understand that water and its quality are characterized in several other ways beyond salt‚ fresh‚ and tap water. In 1967‚ the Water Quality Act‚ which was an amendment of the Federal Water Pollution Control Act‚ was passed. The Act required

Lab 2 – Water Quality and Contamination Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell‚ Color‚ Etc.) Beaker Observations 1 Water is clear and uncontaminated. 2 All of the vegetable oil goes to the top of the beaker. 3 The water looks slightly cloudy but not too contaminated. 4 The water changed colors with the detergent and was clearly contaminated. 5 Water was murky from the dirt. 6 The water did not look as contaminated filtering with oil as it did with

Introduction Why: The goal of this experiment is to determine the water hardness of the prepared unknown water sample. Determining water hardness is a useful test that measures the quality of water for its household and industrial users. Water’s hardness arises from the presence of metal ions – specifically metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium‚

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower.

Hypothesis I believe Red Oak will have the most change in weight in saltwater and the most change in appearance will be Pine in saltwater.

project is to determine whether river water or lake water is cleanest as it relates to tap water. The independent variables being tested in this experiment are the different waters being tested which are river water‚ lake water‚ and tap water‚ which is the control. The dependant variable is which of the three waters are the cleanest as it relates to unfiltered tap water. The purpose of this experiment is to determine what the different aspects of the three types of waters are and how that relates to cleanliness

First‚ the matting was placed on the four slides‚ cover-slips as well as the container of blood on top. Blood containers are in dropper bottles. Number each slide with a wax pencil. A drop of blood was placed on a slide and numbered it slide #1. Slide #1: 1. With the wooden applicator stick‚ dip the end into the blood and place a tiny drop onto slide #1 and put cover slip over it. Slide#2 1. Place 1 drop of 0.9% NaCl with the drop of blood (use the filter paper to absorb excess liquid). 2.

Take the 100ml glass beaker and place it under the water tap’s opening‚ the place where the water comes out from‚ then turn the tap on. Do not turn the tap off until the water inside the beaker reaches the 50ml mark‚ to ensure that there is only 50ml of water in the 100ml beaker. Then take the beaker and place it somewhere safe on the table. After that take the scale and plug it’s wire in the socket‚ then
