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

4A.2 RRL 4A.2.1 Coagulation of Proteins Coagulation of protein refers to sticking together‚ like a blood clot‚ usually as a result of denaturation or coming out of solution due to abnormal ionic strength or a change of solvent. Definite characteristics of the proteins are changed when they are coagulated‚ among which is loss of solubility in water and dilute salt solutions. In some instances and under certain conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2

forms as more sodium hydroxide was added to the unknown substance the possible cations include: Aluminium‚ Lead (II) or Zinc. Furthermore if a white precipitate forms that does not dissolve as more ammonia solution is added it could mean the cation could be Aluminium‚ Lead (II) or Magnesium. This therefore means that further tests would need to be carried out in order to identify the aluminium. Following the Cation tests we found that sample C was copper as the addition of dilute sodium hydroxide solution

Sodium Sodium is the major positive ion (cation) in fluid outside of cells. The chemical notation for sodium is Na+. When combined with chloride‚ the resulting substance is table salt. Excess sodium (such as that obtained from dietary sources) is excreted in the urine. Sodium regulates the total amount of water in the body and the transmission of sodium into and
