Q1. Why should a four place analytical balance not be used in weighing a sample if the manual requests only one decimal place accuracy? Ans. We use the analytical balance where we need to weigh the small amount which needs a high degree of accuracy. Whereas‚ the manual requests only one decimal place accuracy which is not that much important and the time is consumed more to use the analytical balance with four decimal places. Q2. How is the pH meter calibrated? Ans. Firstly‚ The pH meter is calibrated

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate

Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due to their

Corinne N Bryant May 2‚ 2013 University of Phoenix The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For example‚ one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able

Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins

Fermentation Lab: Conclusion & Evaluation of the Effect of Type of Carbohydrate on Amount of CO2 Produced IB Biology/Topic: 3.7 05 February 2013 Question: Which type of carbohydrate‚ glucose‚ sucrose‚ or starch‚ will produce the greatest amount of fermentation over the class period? Why? Hypothesis: If the carbohydrate starch is added to the set up of yeast‚ then it will create the greatest amount of fermentation because starch is a polysaccharides
