C did not mix well with the silver nitrate. The Iodine stayed at the bottom while the silver nitrate collected at the top. Test tube D did absolutely nothing‚ but get a little cloudy 5. Conclusion: The purpose of this lab was to see how silver nitrate affects the reactive Halogens and to see if it formed a precipitate. Most results were the same where a precipitate formed. Some took longer than others to form where as others had no effect to the silver nitrate. Two ways to improve the lab would

Puts ‘Iowa Nice’ to a Test‚ and Dead Zones‚ all share important reasons to what is happening. A huge problem that is dealing with our water is nitrates‚ which is a serious acid and is making our water very unhealthy. All of these articles each share important reasons to why nitrates are so bad and the effect it has on people. Some problems are‚ that nitrates are costing cities way too much money‚ the struggle it puts on farmers‚ and the fact it is one of the causes to eutrophication. After reading

Quaternary ammonium compounds‚ QAC‚ are ingredients found in household products such as fabric softeners‚ detergents‚ disinfectants‚ and hair products that consist of dialkyldimethylammonium compounds (DADMC)‚ benzylalkyldimethylammonium compounds (BAC) and alkyltrimethylammonium compounds (ATMAC) (Li and Brownawell 2010). While trying to find the reason why these rivers keep getting contaminated‚ Brownawell found out that the wastewater areas found in surficial sediments around the Hudson River

Effect of seed germination Purpose: To see the effect of an acid introduced during seed germination‚ on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better‚ and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the

Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

Introduction Germination is the very beginning of the plant’s life; where it transitions from being an embryo in a seed to breaking out and becoming a little stem. There are many factors that affect the germination of seeds which include the PH level of the soil‚ the amount of water in its environment‚ the amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was

The results for nitrate were inconclusive‚ there are traces of nitrate in wells 15‚ 20‚ 23‚ and 21 but we couldn’t find the source. We believe that number 15 is the source but there is very little amount of pollutants in the water to make the solution turn black. Wells 15‚ 20‚ 23‚ and 21 when tested for nitrates‚ the iodine changed to a yellowish blackish color. The hypothesis was not supported‚ well number 26 did not test positive for any of the pollutants. The first well tested was well number

Justification Paper Jim Lammers There is no disputing the fact that performance enhancing drugs have the potential to raise the level of competition in athletics. The goals in sport can be boiled down to higher‚ farther‚ and faster; therefore in order to improve competition it is necessary to make athletes bigger‚ faster and stronger. Professional athletes (not collegiate or interscholastic) should be allowed to make choices in their training regimen which will make them better prepared to do the
