Module 7 Exam Review ANSWER KEY 1. Define acid. (7.01) An acid is a substance that produces hydrogen ions‚ H+ or hydrodium ionsH3O+ in solution. 2. Compare the three theories of acids. (7.01) An Arrhenius acid is a substance the increases the concentration of hydrogen ion‚ H+ or hydronium ions H3O+when dissolved in water. You must have water. A BrØnsted-Lowry acid is any substance that donates a hydrogen ion‚ H+ to another substance. A Lewis acid is any substance that accepts a lone pair

other diseases (Babar et al‚ 1988; Oliveira et al‚ 1999). Thus‚ the effect of various conditions on trypsin activity is of great interest and is further investigated here. The effects of enzyme and substrate concentrations‚ as well as the effects of pH‚ on the initial rates of BAPNA hydrolysis by trypsin are investigated. Additionally‚ the inhibitory activity of the Jack Beans trypsin inhibitor is determined. This type of protease inhibitor in plants (particularly seeds) is widespread and well studied

determine the identity of this unknown acid. Both values were found by preparing the unknown acid solution‚ preparing a buret‚ titrating the acid solution with the strong basic NaOH solution from the previous experiment‚ and determining the pH at various points using the pH meter. The formula weight of our unknown acid was found to be189.93 g and the pKa was 7.2 and 7.05 using two different methods. We were able to conclude that our proposed identity of our unknown acid was MOPS‚ which had a formula weight

Respiratory Case Study The following case study is of a 37-year old Hispanic male weighing 145 lbs and 70 inches tall found unconscious by his girlfriend. According to her he was unconscious for about 15 hours and she was concerned because he would not wake or respond and was breathing shallow and slow. She then called 9-1-1. The patient entered the ER by emergency vehicle and on my initial assessment Pt had an altered mental status‚ was very unresponsive showing symptoms of a possible drug overdose

Alterations in Fluids‚ Electrolytes‚ and Acid-Base Balance Composition & Compartment Distribution of Body Fluids ← Body fluids are distributed between the intracellular fluid (ICF) and extracellular fluid (ECF) compartments. The ICF compartment consists of fluid contained within all of the billions of cells in the body. It is the larger of the two compartments‚ containing approximately two thirds of the body water in healthy adults. ← The remaining one third of body water is in

water bath and measuring the desired temperature using a thermometer. PH: I will make sure that the pH is stable (constant) and only the temperature varies this is to be done by using buffer in every test tube so as to maintain pH balance for each beetroot sample and insure that pH does not become a variable. PH is important for maintaining the integrity of the cell membrane as integral proteins can denature upon change in pH. Also‚ presumably the buffer will have the right concentrations of salt

Determination of the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction
