Experiment ANALYSIS OF SODA ASH The CCLI Initiative Computers in Chemistry Laboratory Instruction LEARNING OBJECTIVES The objectives of this experiment are to . . . • understand the titration curve for a diprotic base. • use the titration curve to calculate the percent of Na2 CO3 in an unknown sample of soda ash. BACKGROUND Sodium carbonate is an important industrial chemical. It is used in the manufacture of soap‚ glass‚ paper and as a source of alkalinity‚ that is‚ as a

ABSTRACT What is the fastest way to cool a soda? In this experiment‚ 8 cans of soda were used to determine the fastest method the cool the can of soda. The four alternative methods were the freezer‚ the refrigerator‚ ice cubes‚ and also an ice bath. Using 2 cans for each method‚ and measuring the temperature at increments of 5 minutes‚ the experiment was complete when the temperature stabilized. In conclusion‚ the fastest way to cool a soda was the soda in the freezer at -2 degrees Celsius. The

Darry and Soda had different points of view on how to interact with their brother Ponyboy. On page 2‚ the books states‚ “Soda’s never hollering at me all the time the way Darry is‚ or treating me as if I am six instead of fourteen.” From this quote‚ the reader is told that Darry treats Ponyboy differently than Soda. It can be inferred that Darry is more strict with Ponyboy while Soda may not be as strict. On the other hand‚ “Soda’s always happy-go-lucky
