Calcium carbonate

Eggshells are made up of a brittle white substance called calcium carbonate, which is also found in cave stalactites. Along with calcium carbonate is the remaining five percent calcium phosphate, magnesium carbonate, and soluble and insoluble proteins (Senese, 2010). The shell is covered with over seventeen thousand tiny pores allowing air to pass through. The semipermeable membrane…

¾ inch of the Copper(II)Carbonate was placed into a test tube. The test tube, by means of a clamp, was fastened to a ring standard to be heated by the Bunsen Burner. A one hole rubber stopper fitted with a glass tube was fitted into the top of the test tube. A measurement of 5 ml of the Limewater was placed into a graduated cylinder. With test tube holders, a separate test tube was held over the end of the glass tubing to collect the gas produced. The Copper(II)Carbonate was heated until it…

carbon dioxide in the ocean as carbonate ions which are an important building block of structures such as sea shells and coral skeletons decreases. Consequently, insufficient carbonate ions present in the ocean can make building and maintaining shells and other calcium carbonate structures more difficult. Other than that, lower pH of the ocean menaces the marine life such as corals, mollusks, and crustaceans as they face a great challenge when their calcium carbonate shells or skeletons dissolve…

Did you ever wonder what happens to your teeth when you drink sugary drinks? If you didn’t know already, drinks like soda, coffee, sports drinks, etc.. are known to be bad for your teeth. But what is in these drinks that cause damage to your teeth? Your mouth feed on sugar, and when they do, they also make acids. Too much acid in your mouth can eventually damage the enamel on your teeth, leaving your teeth vulnerable to tooth decay and cavities. Therefore, acid from soda and produced…

Ocean acidification is detrimental to calcium carbonate life. As CO2 is absorbed into the ocean, it has a chemical reaction with water and forms carbonic acid, lowering the pH. This acid reacts with the calcium carbonate that many shellfish need to build their homes and protection, forming a different type of molecule, and depleting the ocean’s calcium carbonate resources. While it was obvious in our lab that our four mollusks, wrinkled drill, cowrie, small oyster, and large oyster, were to be…

eat away all the healthy minerals like the phosphate mineral and calcium in the tooth enamel which will end up causing the enamel to wear out due to the acidic levels in foods and drinks. But however, according to the website Bfsweb.org again, “once the plaque acid has been neutralized, the minerals can return to the enamel surface – a process called remineralization” which is just “the restoration of lost mineral elements, as of calcium salts to bones or teeth” according to the dictionary. The…

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 calcium (Smolin et al., 2015). Although label 2…

In the first three trials, Calcium Chloride was the limiting reagent and in the last trial Sodium carbonate was the limiting reagent. The moles of CaCO3 produced for each trial was 0.0008113moles, 0.001188 moles, 0.0004476 moles and 0.0002907moles respectively. The mass of product measured for each trial was 0.0812g, 0.1189g,…

and corals are among those affected. When the carbon dioxide binds with water molecules to create carbonic acid, the hydrogen ions broken down from carbonic acid bond with carbonate ions to form more bicarbonate. Unfortunately, shell possessing organisms also rely on carbonate ions to create calcium carbonate. Calcium carbonate is the building block these organisms use to build their shells. This results in weaker shells of shell possessing organisms. The oceans acidity can also result in…

There are no doubt many threats to our oceans and waterways at this point in time. However there is one major threat to water quality that humans are responsible for. When we burn fossil fuel, there are many gaseous compounds released into the atmosphere. Doesn’t sound that bad does it? However, when some of these compounded gases react with water, the water is now acidic. The gas that is produced when burning these fuels is carbon dioxide (CO2). Ocean acidification is when carbon dioxide…
