Phenolphthalein is often used as 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…

This essay illustrates the classification of antagonists according to their characteristics. The classification of antagonists is divided into two main categories, receptor antagonists and non-receptor antagonists. In receptor antagonists, it would be divided into competitive antagonists and non-competitive antagonists. In non-receptor antagonists, divided into chemical antagonists and physiological antagonists. In different categories, there are different examples to support the feature of the…

Abstract The main goal of the buffer capacity experiment was to analyze how the addition of acid or base and dilution affected the measured pH. The results showed that when the buffer systems were under acidic conditions their pH values decreased and increased when exposed to a basic environment. The main goal of the ionization of the amino acid experiment was to titrate an unknown amino acid with a strong base in order to produce a titration curve. The titration curve was used to evaluate the…

Gluskin 6 Abstract: This experiment attempts to answer the question of whether an increase in a succinate concentration (a component of the Krebs cycle) will lead to an increased rate of cellular respiration within a cell. We measured the amount of electrons given off by the succinate to fumerate redox reaction by using DPIP. DPIP is an electron acceptor that takes the place of FAD by accepting the electrons and turning from its oxidized blue state to its reduced clear state. We…

Thompson. His name was Ernest Rutherford and he discovered the positively charged particles in the atom, called protons. He discovered them by firing alpha particles at a very thin sheet of gold foil. Alpha particles are quite large and they were traveling at such high speeds in the experiment that Rutherford and his colleagues believed that they would pass right through…

you can almost say it is a waste of time. Numerous of people have said they should be taking a lab that they will not be using in there next stages in life. Will an accountant be using astronomy or will a history teacher be naming the neurons and protons in a object. I bet not there is no need to. We could be taking more classes about our major and learning about stuff that will contribute to our futures. High school was for taking random classes to meet the requirements and to find out what we…

which contains highly negative charge through out the backbone, histone is positively charged in order to interact tightly with the DNA. These positively charge amino acid will become neutral at a very high pH acting as an acidic residue giving away protons only in a very basic environment resulting in the pI of 11.31. According to the two examples, the protein composition is not evenly distributed as the amino acids are represented in different frequency. Due to this variations, each protein…

Targeting solid tumors - primary & metastatic - irrespective of their anatomical location in the body or pathological sub-type – and permeating drug molecules into the targeted tumor mass, will improve therapeutic outcomes and reduce life-threatening systemic toxicities induced by routinely administered chemotherapeutic regimens. Creating molecular dimension-specific temporary pores in the cell membrane using precisely computed, safe radiofrequencies (RF) from an external source, to…

Rationale I decided to turn this lesson into a flipped lesson as the topic on ionic bonding is something very microscopic and I feel it would help students to develop a more concrete understanding of an abstract topic. By recording the lecture which includes a step-by-step guide on drawing a dot-and-cross diagram, the weaker ones will be able to study at their pace and choose to pause or rewind should they not understand. This helps them to understand the concepts better, as opposed to going…

and highenergy protons and heavy ions waves, also known as cosmic rays. Many of these particles are with the size smaller than atoms but are travelling at almost the speed of light and containing extremely high energy. Particles from the sun are released during solar activities like solar flares or coronal mass ejections. The total energy release from a single solar flare can be equal to more than a million of 100-megatons hydrogen bombs exploding at the same time. Energetic protons are shot out…
