Chemical Formulas and Chemical Equations Purpose: To study different types of chemical substance equations and to conclude if a reaction move ons when two compounds be combined. When reactions occur you should and then(prenominal) be able to predict the products which are formed. Procedures for serial A-E series A: quaternion streak solutions and four reagents are added together making 16 reactions. You note the appearance of all in all the solutions before and after the reactions and to a fault noting if precipitates are formed. Results base in data tables. Series B: allure spues of reagent, 2M HCl, is added to distributively of the three see solutions and one test unattackable noting the results. Results frame in data tables. Series C: One capitulation of .2M NH (aq) is added to quintette drops of severally(prenominal) of the four test solutions and results are recorded. succeeding(prenominal) you add quin more drops of ammonia solution to s everally of the test solutions, mingle contents and record results. Finally, you add five more drops of 6M NH (aq) to individually solution, mix and record results. Results order in data tables. Series D: Five drops of 6M HCl is added to each(prenominal) of the four consentient metals. Results found in data tables. Series E: amplify six drops of each of the four test acid solutions to the four test tubes.
suming two drops of the universal indicator you note the pH of each test solution using a calibration card. You then add three drops of 1M NaOH reagent to each of the solutions, stir, and note pH level. Add another three, then six, then a! nother six drops of NaOH to each solution stirring and noting the pH each time. Results found in data tables. Conclusion: When combining an acid and a base, a salt, gas, and pissing is formed. When combining a reactive... If you want to get a bountiful essay, order it on our website:
