3.3.1.2 Electrical conductivity (EC):
EC were measured by using conductivity meter (HACH model HQ14D) as Mihayo and Mkoma (2012) method.
3.3.1.3 Ferrous (Fe++):
Ferrous was determined by Spectrophotometer (DR 2800) using 1,10 phenanthroline powder pillows. The wavelength dial was rotated until the small display shows 510nm. The same previous steps of apparatus adjustment were followed and the result of Fe+2(mg/l) was recorded as described by APHA, AWWA and WEF (1999).
3.3.1.4 Manganese:
Manganese was determined by Spectrophotometer (DR 2800) using periodate oxidation powder pillows. The wavelength dial was rotated until the small display shows 525nm. The same previous steps of apparatus adjustment were followed and the result of Mn+2 (mg/l) was recorded as described by APHA, AWWA and WEF (1999).
3.3.1.5 Aluminum:
Aluminum was determined by Spectrophotometer (DR 2800) using Aluminum powder pillow method. The wavelength dial was rotated until the small display shows 525nm. The same previous steps of apparatus adjustment were followed and the result of Al (mg/l) was recorded as described by APHA, AWWA and WEF
Chem 100 Final Lab Report
1366 Words | 6 PagesA spectroscopy curve was produced of the acid and the absorbance of the unknown mineral could be obtained in order to find what that unknown copper is. Through these methods there is not preferred method when it comes to finding the percentage of an unknown substance, but which is more effective in accurately depicting what that unknown substance is. Standard deviation plays a major part in this experiment to help balance out and find the mean of the unknown substance to help constitute what it is. Through this the difference between smelting and roasting is that one produces a metal from its ore and the other drices off the carbon to obtain an
6.03 Calorimetry Lab
775 Words | 4 PagesThe absorbance and the maximum wavelength of all eight standard solutions were determined using the same spectrophotometer in this section. First, approximately 3 mL of each solution was added into a cuvette using a plastic pipette. The solution was added until the level reached the frosty part of the cuvette and any bubbles were dislodged by gently tapping the cuvette against a hard surface. Then, a Kimwipe was used to clean the exterior of the cuvette. Once cleaned, the cuvette was transported by only holding the top edges.
Metal Cations In The Crucible
90 Words | 1 PagesMetal cations can be identified based on the colors they emitted off when heated in a flame.1 When atoms of the ions that were tested are excited, their electrons move up to higher levels of energy.2 When the electrons relax and return to the original states, they emit photons of specific energy creating wavelengths of light that produces colors.3 The test wire and Bunsen Burner were used to excite the solution in the crucible. The standard metal cations that were tested and their outcomes are as shown in Table 1.

528 Words | 3 PagesFrom the AA spectrometer’s readings (conducted by Dr. Stephanie Le Clair), the absorbance was calculated for the Ca2+ and Mg2+ which were dissolved in the sample connected to the spectrometer through a tube. Following testing, graphs of light absorbance versus metal ion concentration were created, and the obtained equations from the trend line were used to translate the values into the corresponding concentration of CaCO3 (see

Buying Bottled Water
575 Words | 3 PagesThe article “Buying Bottled Water For Your Health, Stop It,” by Katie Herzong discusses the harm of buying bottled water. As mentioned in the article buying bottled water is estimated to be 2,000 times more expensive than using tap water. Not only is buying bottled water more expensive, but also bottled water produces fossil fuels within the environment that will be put into a landfill where it will not decompose. To better understand the damage Doctor Sanaz Majd examined the risks of bottle water compared to tap water. Her interest originally sparked when her twins were born premature, and the doctor informed her that she should avoid mixing formula with bottle water.
Summary Of Thirst: Fighting The Corporate Theft Of Our Water
291 Words | 2 PagesSnitow and Kaufman’s study was on the water crisis in the United states and the impacts it is making. People don’t realize this, but the water crisis has become more and more of a problem in the United States. Snitow and Kauffman give a lot of valuable information on topics such as making water private. This privatization of water is allowing for companies and corporations to take control of water rather than it being a public resource, like it is supposed to be. In the text it says, “The conservative agenda of small government, deregulation, and privatization has given big business an opening to create a private water market to replace a public service.”
Unknown Compounds
1027 Words | 5 PagesThe probe was cleaned with distilled water and dried before placing into the unknown solution. The solution was .500+-.0005g of the unknown compound dissolved in 20+-0.5mL of water contained in a 40 mL beaker. A 10 mL graduated cylinder was used to measure accurately. The conductivity of the unknown compound was recorded and then the probe was removed and cleaned. Next, the probe was placed in potassium nitrate solution.

Empirical Formula Lab Report Essay
1161 Words | 5 PagesEmpirical Formula of Magnesium Oxide - Lab Report Background Information/Introduction: The aim of this lab is to determine the empirical formula of magnesium oxide by converting magnesium to magnesium oxide. As an alkali earth metal, magnesium reacts violently when heated with oxygen to produce magnesium oxide and magnesium nitride as a byproduct. In order to obtain only magnesium oxide, distilled water was added so that magnesium nitride will react and convert to magnesium hydroxide. Further heating then oxidizes all of the magnesium into magnesium oxide.
