Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)

1 DESIGN 1.1 Defining the problem Focus / Research question How does osmosis work and what effect will this have on the raisin at different sucrose concentrations? Hypothesis The raisin in the beaker with most diluted sucrose solution will gain the most mass‚ therefore the control (0% sucrose solution) should be the most successful (in relation to the aim.) Background Information / theory Osmosis may occur when there is a partially permeable membrane‚ such as a cell membrane

Executive Summary The recent acquisition of French energy company Alstom by General Electric has made a lot of headlines in the world recently. This is one of the largest acquisitions by the General Electric and involved a lot of complexities. The Alstom’s board of directors was ready to cut the deal with General Electric but French government has made this deal as the national pride and tried to interfere. They opposed this deal on the ground of loss of jobs in France but in reality the French

different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would move from the

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

Britney The Effects of Bullying on Children Bullying is a serious problem that is present in our world today. There are many reasons why kids bully other kids‚ ranging anywhere from “just for fun”‚ to having low self-esteem‚ or a rough home life. More than half of the population has been or will be bullied sometime during their school-age life. The effects of bullying on children can cause social isolation or even suicide.
