Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

Bargaining power is the ability to influence the setting of prices. Buyer power refers to the ability of customers of the industry to influence the price and terms of purchase. The bargaining power of customers is also described as the market of outputs. The ability of customers to put the firm under pressure‚ which also affects the customer’s sensitivity to price changes. Bargaining power of buyers occurs when leverage is given to the buyer and demand for lower prices‚ increased quality and more

The Federalists Papers were made to explain why the central powers should be more powerful than state powers and how the central powers should be the supreme or absolute power‚ and the Anti-Federalists papers were made to oppose these views and explain why the state powers and the central powers should still have be equal. The response by the Federalists was more persuasive. The Federalists Paper #10 was written by James Madison. The document was titled “The Union Against Domestic Faction and Insurrection”

Case Study 2 Professor A. Van Cauwenbergh of Antwerp University‚ in a paper presented at the Tenth Anniversary Conference of the European Institute for Advanced Studies in Management‚ presented four revisions to traditional Management Theory. In summary‚ the revisions are: (1) The initiative for the renewal and adjustment of the activities of a firm should come from the different levels in the management hierarchy. “Strategy is not a privilege of top management”. (2) Firms‚ especially big firms

The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

we were always given the option to live on base or off. The answer has always been the same‚ off base. I enjoy living off base because we have more freedom‚ a sense of normalcy‚ more income‚ and a better way to experience the culture in Spain. Being able to live off base has always been a better experience for us and we always enjoy the different homes we are able to choose from. First I enjoy living off base because we have more freedom. Being off base we still have to follow certain rules of the
