Acid-base chemistry

an indicator in acid base reactions. The reaction used in this lab is: C_20 H_14 O_(4 (aq))+46 NaOH_((aq))→46 Na_( (aq))^++20 H_2 CO_(2 (aq))+10 H_2 O_((l)). Phenolphthalein and sodium hydroxide react to form carbonous acid, water, and Na+ ions. This reaction is a neutralization reaction, where phenolphthalein, a weak acid, reacts with a strong base, sodium hydroxide. When phenolphthalein is put into a basic solution, it turns pink. The phenolphthalein ion is pink, and when a base and…

I request to take AP Chemistry because I want to major in Biomedical Engineering. By taking AP Chemistry, I will be a step closer for preparation of my future profession. This year as a sophomore I am taking AP Biology, AP Psychology, Honors Pre-Calculus, Physics 1, and Chemistry 1 simultaneously without any issues or problems. I also have taken AP United States History as a freshman along with seven other courses. Because of this, I understand the demanding nature of these AP courses and the…

The research work regarding the chemical processes within/relating to living organisms is said to be biochemistry, also known as biological chemistry. The complication of life can occur during biochemical process, if we control the information flow through biochemical signaling and through metabolism chemical energy flow. Various study fields like botany, medicines, genetics, Etc.which are areas of life science, are engrossed in research related to biochemical because biochemistry has made it…

fertilizers, rodenticides, and food preservatives.Turbidity is caused by sediment or other pollutants and causes the water to appear murky or cloudy. (2008) The pH can be changed by some of the rocks in the water, such as limestone which neutralizes the acid in the water. (Oram, no date) “Nitrates are forms of nitrogen and is found in several different forms in terrestrial and aquatic ecosystems”. Nitrates in the water are caused by wastewater treatment plants, runoff from fertilized yards,…

My interest in biology and chemistry stems from the fact it explains a world that’s not visible to the eye, but is a key role to life. This sparked my interest in the intricacy of the human anatomy and physiology which has me curious to the research required. The desire to pursue a career in helping others, but also to explore science at a greater depth. I believe biomedical science will enable me to broaden my perspective and give me a solid foundation of knowledge and skills required for…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

on it which would have been removed with the stick. It is less clear why the benzoic acid was overproduced. Some of the organic layer may have been drawn off with it, but the vacuum filtration should have left only the benzoic acid. There could have been an error in weighing the filter paper before the procedure. There also could have been contaminants in the basic extract, causing more than just the benzoic acid to be filtrated. There is also the chance that too much starting material was…

a pH of seven, however most water, either from the tap or rain water, are not neutral (they do not have a pH of seven) instead it varies slightly and normally ranges from about 4.0 to 5.5 on the pH scale, which shows that they are slightly acidic. Acid rain is due to the chemical reaction that takes place…

Nitrogen affects the growth of many proteins by all aquatic organisms. Oxygen is used by the organisms to breathe. Carbon dioxide is used by seaweed and other algae during photosynthesis. Also the levels of carbon dioxide affect the balance of acids and bases in saltwater when it produces carbonate ions under specific conditions (Duke University, n.d.). There is a lot of carbon dioxide in the ocean because of the burning of fossil fuels, coals, oils, and natural gases. The dumping of our waste…

statistics to anything that had to do with people. I means that’s I’m pure and completely myself. It is okay for me to be as bitter and acid as I was designed to be. It also means that I am at my strongest. I am at my strongest emotional and mental state. This does not mean that being around people of lesser pHs weaken me. It just means that my friends that are bases can calm me. What I have learned is that I must be strong and when I am left alone is that…
