Lab Report # 11 By: Andrew Hoitt CHEM 105 Lab 11/29/2012 Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions

important to the success of the production. In this experiment‚ sodium hydroxide and ethyl acetate react in tubular flow reactor.Both of the reactants fed to the reactor at equimolar flowrate for a certain time.The reaction is carried out at different volumetric flowrate.The conductivity value of outlet stream is measured to determine the conversion achieve at different retention time. The retention time is highest for the lowest flowrate. The result shows that the conversion is increases as the residence

market‚ increase costs and reduced share price Eli Lilly must implement a new manufacturing strategy in order to remain competitive within this market. Alternatives that have been considered include constructing a flexible facility; increasing volumetric efficiency of existing plants; building the manufacturing facilities at a much earlier stage; or reducing asset base. After thorough analysis of the potential benefits and drawbacks of each alternative‚ the BioPHORs recommend a manufacturing strategy

Test tubes are for holding small samples or for containing small-scale reactions. Test tube holders are for holding test tubes when tubes should not be touched Tongs are similar in function to forceps but are useful for larger items. Volumetric flasks are used to measure precise volumes of liquid or to make precise dilutions. Wash bottles are used for dispensing small quantities of distilled water. Watch glasses are for holding small samples or for covering beakers or evaporating

tonal modelling‚ David illustrates three dimensionality‚ which is therefore very naturalistic. Tonal modelling is shown through the deep shadowing in forms of the painting. This deep shadowing creates a more believable volumetric space. For example‚ we get a sense of the figures’ volumetric space through the shadowing in the folds of the figures’ robes; which suggests the outlines and contours of the figures’ bodies. The composition in Belisarius Begging for Alms draws attention to the key features
