  • Essay On Co2

    Since the beginning of the industrial era carbon dioxide or CO2, concentrations have been dramatically increasing. Today we are facing the highest amounts of CO2 in our atmosphere and in our oceans in over 650,000 years. There are a great deal of effects increased CO2 concentrations will have on this planet. When the ocean absorbs CO2 chemical reactions occur that eventually reduces their pH, carbonate ion concentration, and saturation states of important calcium carbonate minerals. This is known as ocean acidification and with the altering of saturation states coral reefs around the world have suffered a great impact because of this. The ocean is one of the largest natural reservoirs and absorbs one third of the excess CO2 that is directly created from human activities. Coral reefs take up a small percent of the oceans but harbors millions of different species. Coral reefs also provide ecosystem goods and services to 450 million people that live near them. Research is still being done today by monitoring pH levels in the ocean, observing aragonite upwelling on continental shelves, and following CO2 emissions. Carbon dioxide can create several different ions and alter atmospheres in many different ways. When CO2 is discharged it can be absorbed by plants or oceans, or it is released into our atmosphere. When CO2 is absorbed into the ocean it reacts with water and through additional chemical reactions bicarbonates are formed. These bicarbonates contribute to the altering of…

  • Co2 Lab Report

    Reactions similar to this one tend to buffer changes in atmospheric CO2. The right side of the equation indicated that the reaction produces an acidic compound. If adding CO2 to the left side, would decrease the pH of water in ocean. This process is often been described as ocean acidification, where pH of the ocean becomes less and force the pH of water to be acidic. Rather than this reaction there are other reactions between CO2 and non-carbonate rocks which also add bicarbonate into the…

  • Gastroretentive System Of Metformin: Approaches To Effervescent Tablets

    Indore (MP) ABSTRACT Effervescent tablet generally contains in addition to active ingredients, mixture of acids/acid salts (Citric, Tartaric, Malic acid or any other suitable acid or acid anhydride) and carbonate and hydrogen carbonates (Sodium, Potassium or any other suitable alkali metal carbonate or hydrogen carbonate) which release carbon dioxide when mixed with water. Occasionally, active ingredient itself could act as the acid or alkali metal compound necessary for effervescent reaction.…

  • Biological Impacts Of Ocean Acidification

    compiled to see how the organisms fared. In one source, the effects of increased carbon dioxide on Atlantic Cod Gauds Morhua larvae were observed. Three concentrations of water including a control 370 micro-atm, a medium of 1,800 micro-atm, and a high concentration of 4,200 micro-atm were used within the experiment. In the high concentration, seven to forty-six cod larvae were observed with increased otolith growth. However, no major impacts were present on the larvae such as fluctuating…

  • Coral Bleaching Effects

    reactions occur that eventually reduces their pH, carbonate ion concentration and saturation states of important calcium carbonate (CaCO3) minerals. This is known as ocean acidification. With the alteration of acidity, saturation states, and increased temperatures coral…

  • Aspirin Essay

    Introduction The aim of the experiment was to investigate whether different formulations of aspirin would affect its bioavailability. This required the use of normal aspirin tablets, aspirin tablets with sodium bicarbonate, soluble aspirin, and enteric coated aspirin. Depending on which group the students were allocated they administered different formulations of aspirin. The pH and the concentration of salicylate in each urine sample, collected at different time points, was determined after…

  • Hess's Law Lab Report

    2013). It is also used in research of other possible fuels by finding the cost to produce it and comparing it to the amount of energy it will provide to find out if it is a worthwhile investment. The main objectives of this lab are to find the energy changes in reactions two and three then using two and three find the ideal reaction one’s change in energy. The general experimental design is that using a calorimeter you would first find the change in energy of calcium carbonate reacting with two…

  • Gravimetric Analysis Of Calcium Carbonate

    Gravimetric Analysis of a Metal Carbonate Purpose The purpose of this lab is to find the mass of an unknown metal by conducting a double-displacement precipitation reaction, which is our gravimetric analysis. Once we find the precipitate mass, we can then find the molar mass by using the molar ratio given in the reaction equation. Procedure First, we set up the ring stand with a Bunsen burner, put a crucible on top of the pipe stem triangle and heated the crucible for a minute, then let it…

  • 6.03 Calorimetry Honors

    Determining the Percentage Yield of a Chemical Reaction Question: What is the percentage yield of the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of…

  • Back Titration Of Calcium Carbonate In Toothpaste

    1. Synopsis The main aim of the experiment is to find out the percentage of calcium carbonate in toothpaste by using back titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed…
