Gracen Seiler April 7th‚ 2015 Section- 109 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction- This experiment is intended to help find a better understanding of chemical stoichiometry through titrations of NaHCO3 and NA2CO3 with HCl. A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form in a nuclear reaction. Titration is when a measured amount of

ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example in this experiement‚ the analyte that was used was copper in the form of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated‚ and we did this by precipitating it out of the solution. To precipitate out Cu (II) ions‚ NH3 was added dropwise – this is
