A titration is a method where a solution of known concentration is used to determine the concentration of an unknown solution. Typically‚ the known solution is added from a burette to a known amount of the unknown solution until the reaction is complete. Knowing the volume of the known solution added allows the determination of the concentration of the unknown. Often‚ an indicator is used to usually signal the end of the reaction‚ the endpoint. Concentration is the abundance of a constituent divided

Experiment TITRATION OF A COLA PRODUCT The CCLI Initiative Computers in Chemistry Laboratory Instruction LEARNING OBJECTIVES The objective of this laboratory experiment is to determine the molar concentration of phosphoric acid in a cola product. BACKGROUND Titration is an analytical technique used to find the concentration of a known volume of unknown substance by adding a known concentration of a known substance. As the unknown and known substance react‚ we look for a "telltale" indication

Acid/Base Titrations Pre- Lab Questions 1. Using your textbook or a handbook‚ look up the formula and structure of potassium hydrogen phthalate (KHP) used to standardize the solution of NaOH in this experiment. Calculate the Molar Mass of KHP. Molar Mass= 204.22 g/mol Formula: KC8H5O4 2. Using your textbook or chemical dictionary‚ write the definition of indicator. Indicator- a substance added at the beginning of the titration that changes color at (or very near) the equivalence

Part A- Additive Volumes First‚ obtain a dry 10 mL volumetric flask that includes a stopper with it and weight on a digital scale. Be sure to get the mass at the closest milligram. Then‚ pour DI water to the calibration mark of the flask. Place the stopper back and weigh it again on the same digital scale. Once recorded‚ it is okay to pour this water down the drain. Observations: Mass of Empty Flask Mass of DI Water Filled Flask 15.114 g 25.048 g Now‚ put 100 mL of ethanol in a beaker and

question‚ or topic‚ was “Does the level of vitamin C change over time in Orange Juice.” After I viewed the website‚ I got very excited because it had simple step-by-step instructions about how to test the level of vitamin C. On the following page are the directions. I think I am really excited to do this project because it sounds very interesting and fun to do. I hope to prove what the driving question/topic entails. Paragraph 2 – Background (5 Facts) • Vitamin C helps to repair and regenerate tissues

Reflective writing : career talk 1 For me as a bio medical student‚ knowing my major and following vocation was a great concern until I participated in first career talk. On that time I understood the different concepts and functions of biomedical science. Also I should state that it’s vital for every student to know his/her majors’ expectations and base on it work hard to obtain essential features and knowledge. When I entered lecture room on the 4th floor I observed a friendly
