for pH values above 7‚ each of which is ten times more alkaline than the next lower whole value. For example‚ pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8. Primary pH standard values are determined using a concentration cell with transference. This measures the potential difference between a hydrogen electrode and a standard electrode. Measurement of pH for solutions can be done with a glass electrode and a pH

flavorful and nice color. No errors occurred. I think we did really good job this time too. We made 16 boxes for sale which we are expecting to sell all of them in the school farmer market. Conclusion: The cookies that we made during each lab showed most of the benefits and disadvantages of making our own cookies compare buying commercial cookies (saving money‚ healthier version‚ taste‚ and texture). I believe‚ I can use all these experiences that I gained during each cookies labs at home too. Also

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

Section 001 Lab Performed 8th‚ 2012 Lab Report Submitted February 22nd‚ 2012 Abstract The purpose of the lab was to determine the order of reaction for the dye Red #40. By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach completion. By comparing two solutions of dye that have different concentrations

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other
