    Research Question: How does the concentration of the nitric acid affect the the time for the magnesium to dissolve or react. Hypothesis: If the concentration of the nitric acid is lower, the magnesium strips will dissolve slower and each time the concentration acid is higher the magnesium strip will dissolve faster. The reason for magnesium strips to dissolve faster when the concentration of the nitric acid is higher is because the reaction of this experiment is exothermic and when more energy is

    Question 2 - Inosine in AMP catabolism  Introduction Adenosine monophosphate (from now on referred to as AMP) is the lowest energy-containing nucleotide found in living organisms. In its degradation process (Figure 1), several enzymes and intermediates are required, playing important roles that regulate the correct functioning of the overall process. An alteration in any of those participants can cause severe consequences, such as immunosuppression. Inosine is one of those previously mentioned intermediates

    Theory: The acid value can be defined as the number of milligrams of potassium hydroxide required to neutralize the free fatty acids present in one gram of fat. It tells about the measure of rancidity as free fatty acids are normally formed by the decomposition of oil glycerides. The acid value is expressed as percent of oleic acid, lauric or palmitic acid. Principle: The determination of acid value is based on the principle of directly titrating the

  • Acid Rain

    1. List some sources of acid rain. Acid rain is made by a chemical reaction that starts with sulfur dioxide and nitrogen oxides which is the main cause for the harmful effects of acid rain released in the air. These compounds get into the atmosphere where they get mixed and start to react with oxygen, water and other different chemicals to make acid rain. Sulfur dioxide and nitrogen oxide both can dissolve in water. I personally feel that it is because of humans acid rain is so harmful. Over the

    the others were clear. This made it easy to then match D up to Copper Sulfate because of its color. As unknown A and B were added together, lots of gaseous bubbles formed and revealed the fact that that reaction was the reaction between Hydrochloric Acid and Sodium Carbonate because it was the only reaction that produced a gas release. Unknown A and C produced the only yellow, brown precipitate just as the reaction between Sodium Carbonate and Silver Nitrate had previously. This led to the conclusion

The importance of benzoic acid in modern world is due to its uses: the acid and its salts are used as preservatives in food: benzoic acid is globally known as E210 and sodium benzoate as E211. The benzoic acid and its precursors are also used in pharmacy and hygiene products : the shampoo and shower gel that I am using all contain sodium benzoate. With its increasing production I was curious to explore the synthesis methods for benzoic acid and try it in the laboratory

    INTRODUCTION Acid rain or also known as acid deposition are divided into two that is wet deposition and dry deposition. Wet deposition is what always be called as acid rain. Acid rain is a term that any form of precipitation with acidic component, such as sulphuric or nitric acid. Example of acid rain form were rain, snow, fog, hail or even dust that is acidic. Acid rain occur when sulphur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents

    ACID DEPOSITION AND ACID RAIN: Acid deposition is caused by acidic particles and gases that deposit or fall to the Earth. Acid deposition can be wet or dry. Wet deposition is deposition of acidic gases such as oxides of sulfur and nitrogen and acidic particles brought down as precipitation by rain, fog and snow. Dry deposition is dry deposition of acidic gases in the absence of rain or precipitation. Acidity is measured using a scale called the pH scale. This scale goes from 0 to 14. 0 is the most

    If it’s exactly 7 then it is called neutral. Lemon juice and vinegar are both very acidic, while bleach and soapy water are very basic. Opposite to the typical assumption, the pH scale can range from less than 0 to greater than 14 for very strong acids and bases. Brine shrimp are native to the Great Salt Lake. Even though they are used as fish food, they can also represent
