Report of redox titration--- Iodine titrated against sodium thiosulphate Objectives The objective of this experiment is to balance the equation for the reaction between sodium thiosulphate and iodine. Principle As the reaction between sodium thiosulphate and iodine is a redox reaction‚ so I make use of this to perform a redox titration‚ iodine titrated against sodium thiosulphate. From the experimental result‚ I can find out the number of mole of the two substances‚ hence I can calculate

Experiment 20: pH Titration: Phosphoric Acid in Cola Drinks Post-lab Assignment or Report The post-lab report for this experiment is due at the beginning of the following lab period. Student notes for the lab will be available on the lab T-Square site. Learning Objectives Students will be able to... • Use a known mass of solid acid to determine an unknown concentration of a basic solution (this process is called “standardization”). • Execute a titration using good‚ reliable technique.

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
Premium Acid Titration PH
Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately

standardized by titration with a solution containing a known concentration of iron (II) ions‚ (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution of iron (II) ions. A solution of oxalic acid is then titrated with the permanganate solution to determine the exact concentration of oxalic acid. Purpose:
