Writing III – Acid-Base Balance Congestive heart failure (CHF) is caused by the inability of the heart to fill correctly‚ eject blood completely‚ or a combination of the two‚ which results in a decrease in cardiac output. Chronic hypertension (CH) is a constantly elevated blood pressure. Peripheral vascular disease (PVD) causes a restriction in blood circulation due to atherosclerosis‚ fatty deposits on the inner linings of the arteries that cause a blockage of blood flow; arteriosclerosis‚ loss

Determination of Total Carbohydrateby Anthrone Method Carbohydrates are the important components of storage and structural materials in the plants.They exist as free sugars and polysaccharides. The basic units of carbohydrates are themonosaccharides which cannot be split by hydrolysis into more simpler sugars. The carbohy-drate content can be measured by hydrolysing the polysaccharides into simple sugars by acidhydrolysis and estimating the resultant monosaccharides. PRINCIPLE Carbohydrates are

The Ford Ka case introduces the fundamental problem of market segmentation and target selection. Ford’s problem does not fit the ‘textbook’ segmentation process since it developed the Ka before determining a target market for it. However‚ this is frequently the case‚ for example‚ when a firm copies a successful product idea (like Ford did) or wants to introduce an existing product in a new market to expand its geographical coverage. The case illustrates that even in this situation‚ market segmentation

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 neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration method. The KHP solution

Which segmentation approach should be used for the Ford Ka? Demographic segmentation was advocated by management due to its historical success and the fact that data was accessible. However‚ demographic focus group results contradicted management’s view. The 40-44 year old group comprised a 32% share. Attitudinal

Abstract By using acid-base titration‚ we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein’s color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of
