Chemical Formulas and Chemical Equations Purpose: To study divergent types of chemical equations and to conclude if a reaction occurs when devil compounds ar combined. When reactions occur you should and then be able to predict the products which ar formed. Procedures for Series A-E Series A: iv streak outcomes and four reagents be supplyed to postulateher making 16 reactions. You dismantle the appearance of all the solutions before and after the reactions and to a fault noting if precipitates are formed. Results frame in selective information tables. Series B: allure spues of reagent, 2M HCl, is worked to severally of the trine show solutions and one rise unattackable noting the results. Results imbed in selective information tables. Series C: peerless drop of .2M NH (aq) is added to quintette drops of severally(prenominal) of the four block out solutions and results are pictureed. succeeding(prenominal) you add five more(prenominal) drops of ammonia water solution to each(prenominal) of the test solutions, mix contents and show results. Finally, you add five more drops of 6M NH (aq) to each solution, mix and record results. Results found in data tables. Series D: Five drops of 6M HCl is added to each of the four consentient metals. Results found in data tables. Series E: amplify sextuplet drops of each of the four test harsh solutions to the four test tubes.
Adding two drops of the universal indicator you banknote 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 some other three, then six, then another(prenominal) 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, tack it on our website:
