Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of water through a permeable membrane. The phrase “permeable membrane” means that the membrane will only allow specific molecules through such a water or oxygen. In Osmosis water will travel from an area of higher water potential or an area of lower water potential. Hypothesis: I think that in this lab‚ osmosis and diffusion will occur between the solutions of different

Exploration How do increasing sucrose concentrations of 0.0 mol dm3‚ 0.2 mol dm3‚ 0.4 mol dm3‚ 0.6 mol dm3 and 0.8 mol dm3 affect the osmolarity point of potato cells‚ where it is investigated how osmosis changes the weight of the potato cells‚ measured by the percentage change between the initial and final mass of the potato? Independent Variable: Increasing sucrose concentrations Dependant Variable: Mean percentage change in mass of potato cells All cells have a protective barrier‚ one which

retains the solids and contaminants in the water. The membrane is the most important part of the system. It very hard to located problems in the membrane. In addition‚ if the membrane is not in perfect condition‚ the system is not working. Reverse osmosis is a kind of filtration. Filtration is an oldest process that consists in the water passing through sand‚ gravel or membrane. Thus prevent the solids and contaminates passing for the other side. The pores of the filters need to be small. The smaller

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)
