Purpose: The purpose of this was to determine the concentration of sodium carbonate in an unknown sample by titration. The solution of hydrochloric acid was prepared and standardized using Na2CO3. Observations: Week 1: Standardizing hydrochloric acid using sodium carbonate with bromocresol green indicator Table 1: Titration of sodium carbonate using hydrochloric acid Trial | Mass of Na2CO3 (g) | Burette Reading (mL) | Final Volume of HCl (mL) | | | Initial | Final | | 1

report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through displacement

I. Title Identification of an Unknown Plasmid In this experiment‚ we determined the phenotypic capability of an unknown plasmid along with its size. With the use of gel electrophoresis‚ we analyzed the gel photograph by using a standard DNA marker‚ Lambda HindIII‚ and came to a conclusion based on our results. II. Abstract Two experiments were done to identify an unknown plasmid. The success of these experiments came from the use of modern day technology involving gel electrophoresis
