Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of […]

Abstract This experiment aimed to monitor the efficacy of the Barley Amylase Enzyme in breaking down starch in solutions with increasing neutral pH levels. The experiment involved simultaneously mixing tubes containing a reaction solution of Amylase enzyme and starch. The reactions were then stopped using I2-KI at two-minute intervals. To ensure accuracy, each trial was […]

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle, particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ? ————? Lactate + NADThe reaction above can […]

Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5. 5. In this experiment, the starch is used as a substrate […]

Enzyme Activity Lab Hypothesis: Are enzymes reusable? Yes, enzymes are reusable. Which of the following do you think contain catalase? [Manganese dioxide, chicken meat, apple, carrot, potato, or chicken liver] I think that the manganese dioxide, apple, and carrot contain the catalase. Would grinding the materials affect enzyme activity? I think that grinding the materials […]

Aim and Hypothesis: My aim in this experiment is to compare the enthalpy change of neutralisation by titration, for each reaction between the following 3 acids:Sodium hydroxide (NaOH) and hydrochloric acid (HCl) – pH 1Sulphuric acid (H2SO4) and NaOH – pH 1NaOH and Ethanoic acid (CH3COOH) – pH 2.88 – 3I predict the reaction between […]

The lecturer handpicked the optimal data sets for comparing pH measurements of different soil types with and without 0.01M calcium chloride. Table 1 displays that sand exhibits the highest pH, followed by organic matter, compost, 3:2 soil, and sedentary soil with the lowest pH. Soil pH is impacted by acid and base-forming ions including hydrogen […]

Investigating Membrane Permeability Reason for choosing beetroot as the object of experiments Beetroot is usually used as the membrane ‘disruption’ experiment. It is because of beetroot has more pigments in their vacuole. These pigments show how variables damage the membrane of beetroot. The pigments will be automatically extracted from the vacuole when the membrane is […]

Alkaline water, also commonly known as ionized water, is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer, or “alkalizer” and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon […]

Indigestion is a general term used to describe discomfort or pain in the upper abdomen or chest, which is sometimes experienced while our bodies digest the food we eat. A better and more scientific term for indigestion is dyspepsia. Indigestion is caused by too much acid in the stomach. Indigestion tablets contain bases, which neutralize […]

One of the more common reactions seen in chemistry is the acid/base reaction. The most common result of an acid/base reaction is the formation of water and a salt. Such a reaction can be highly useful in the analysis of an unknown acid or base. By titrating the unknown analyte with a standard reagent, several […]

Metal Zinc Blobbing Magnesium Fizzing Bubbling Iron Copper Reactions with Indicators Speed of Reactions With Metals Observations continued: In my observations, in data table 1, the only solution that reacted with the red litmus paper was Noah. All three solutions reacted with the blue litmus paper; HCI and HACHURE turned the blue litmus paper red, […]

Honors Chemistry Titration Lab Write-up Introduction Titration Is a method, which Is meant to find the concentration of either an acid or a base by adding a measured amount of It to a known volume and concentration of an acid or Basel . Titration starts with a beaker or Erlenmeyer flask containing a very precise […]

An investigation into the total acid content of assorted brands of lemon and lime soft drink Abstract: The aim of this experiment was to determine the total levels of carbonic acid concentration in 3 differing brands of lemon and Lime soft drinks. Research Question: Does the acid content in three different lemon and lime flavored […]

Abstract: The aim of the experimental investigation was to gather four dissimilar water samples and test them in several different methods to see which water sample had the best quality. The tests that were used were that of: A fecal chloroforms test, phosphate test, nitrates test, pH test, dissolved oxygen test and a total dissolved […]

Aim: To calculate the enthalpy change of naturalization of the given pairs of acid and base. Theory: When alkali neutralizes an acid. A salt and water are formed. Aqueous hydrogen Ions, from the acid react with the hydroxide ions, OH-(as) from the alkali, forming water. Ionic equation: H+ (as)+OH- (as) -9 H2O (l) The Identity […]

Abstracter is important substance for all living organisms. The physical and chemical properties of water play a central role in biological structure and function of the organism. The nomination ability of water to form H+ and OH- ions make it very unique. The hydrogen-ion concentration of biological system is usually preferred as the pH system, […]

There are four significant regions in titration curves: the initial point, pre-equivalence point, equivalence point, and post-equivalence point. Each region’s characteristics are related to the pH results obtained, and the points are named according to their position relative to the equivalence point. The equivalence point is where the solution becomes neutral, which is represented on […]

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base naturalization reaction. We will also determine the unknown concentration of the strong base Noah by its reaction with a […]

The BAG analysis is also seed for monitoring respiratory therapy (again by evaluating the gas exchange In the lungs). Nursing considerations: Your first look at an BAG result might prove to be confusing. Any patient who is critically ill might be given this test at regular intervals. Arterial blood gas determinations will indicate two basic […]

The way buffer does this Is by reacting with the strong acid/base to form a weak acid/base that will barley affect the pH if any effect. Blood is a good example of how buffers work. The pH of blood is around 7. 4 and If It changes by only . 2 It can be enough […]
