chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify a chloride, equal amounts of the unknown solution, 6M HNO3, and AgNO3 are mixed together and if a white precipitate is formed, the test is positive. To identify a sulfate, equal amounts of the unknown, 6M HCl, and BaCl2 are…

To carry out the experiment we need to get caffeine into a solution. We used a solid-liquid extraction by adding 14 tea bags into a 1L beaker with 6g of sodium carbonate, 250 mL of tap water and bringing this to a boil for five minutes on a hot plate. Sodium carbonate is a weak bronsted base, that neutralizes tannic acids extracted from tea, that interfere with the later sublimation operation.(1) We turned the heat off after five minutes, added ice cubes to cool the mixture to room temperature…

CAUTION: It is best not to get dichloromethane on your skin. Gloves are to be worn during this experiment, if improper safety precautions are taken there is a possibility of irritation, and or burning of the skin. CAUTION: Gas will build up in the separatory funnel while you are shaking it, so you must vent the funnel occasionally to prevent the stopper from popping out, causing a mess and possibly getting dichloromethane on your skin. ~During the pre-phase of this experiment it is…

carbon dioxide that hits the ocean’s surface layer combines with seawater, some of the carbon dioxide reacts with the water to from carbonic acid. Carbonic acid separates into hydrogen ions and bicarbonate ions. Then, hydrogen ions combines with carbonate ions forming more bicarbonate ions which makes seawater more acidic. Page 2 Biological Effects on Marine Life In a biology class, I learned about things such as buffers, acids, and bases. I learned that the more Hydrogen molecules…

I would choose the food associated with label 2 more often. This is because it contains 15% of calcium and label 1 contains 0%. This indicates that this food product is more beneficial for the individual since it provides an important mineral. This allows bone health to be maintained and could reduce the risk of complications in the future (Smolin et al., 2015). Also, looking at the sodium content, it is much lower compared to label 1. This could aid in reducing blood pressure with the help of…

Reagents 2,4-dichlorophenoxyacetic acid (2,4-D) (Sigma-Aldrich), 2,4 dichlorophenol (2,4-DCP) (Sigma-Aldrich), ferric sulfate (nH2O) (Carlo Erba), hydrogen peroxide (H2O2) (Carlo Erba), acetonitrile (Sigma-Aldrich) and Milli-Q water were used to perform all the experiments . All the reagents were used without further purification. Natural groundwater samples Samples were taken from groundwater wells localized in a small rural community (coordinates: 3º21’03.38” N, 76º26’24.51”) near to the…

nature, some granites are resin-treated to enhance the color. For this reason, many types of granite have lower abrasion resistance than expected. Limestone Limestone is a sedimentary rock composed essentially of calcite, a mineral of calcium carbonate. The formation processes of limestone differ substantially in the origin of the constituents sediments: these may result (organogenic limestones) from shells or exoskeletons. They can also be formed by the chemical precipitation of salts…

In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…

B” is Na2Co3 (Sodium Carbonate). Again if we look at the color flame picture that I have, we can see that Magnesium is white, and in my color flame test “Substance A” didn’t show any colors when we put on the flame. This means that since Magnesium is colorless or white “Substance A” is MgSo4 (Magnesium Sulphate). Teacher Jin excluded “Substance D” because it was not pure enough to show or exhibit enough information, so that we can say “Substance D” is CaCo3 (Calcium Carbonate).For example in the…

Introduction The seven soil formation factors have created unique soils throughout Saskatchewan. Through time soil processes such as additions, losses, translocation, and transformations have continued to form soils and make different horizons. Two catena's in Saskatchewan, one in the prairie and another in the boreal forest, were examined and classified into taxonomic group. The objective was to identify, compare, and contrast the major soil formation factors, morphological features, and…
