Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

ABSTRACT Firstly‚ the objectives of the experiment are to observe the characteristics of the flow and to compute the Reynold’s number. Using the Solteq Osbourne Reynold’s Demonstration (model FM 11) in this experiment‚ with different of water volume flowrate‚ the characteristics of the flow could be determined. The rock inside the stilling tank are to calm the inflow water so that there will not be any turbulence interfere with the experiment. The water inlet and outlet valve and dye injector utilized

With Giotto‚ he personally took the flat world of what was the thirteenth century art and then transformed it into a volumetric sphere for the real world. Finally with the work of Raffaello Sanzio da Urbino‚ known as Raphael‚ it resulted with a acumination of all the developments achieved in the arts of naturalism during the high Renaissance.
