Chemical Formulas and Chemical Equations Purpose: To study different types of chemic equations and to conclude if a reaction surpasss when two compounds be combined. When reactions occur you should and consequently be able to predict the products which are formed. Procedures for series A-E serial publication 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 embed in data tables. Series B: allure spues of reagent, 2M HCl, is added to respectively of the three hear solutions and one test unattackable noting the results. Results effect in data tables. Series C: One brush off 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 v more drops of ammonia solution to separatel y(prenominal) of the test solutions, pleat contents and record results. Finally, you add five more drops of 6M NH (aq) to each(prenominal) solution, mix and record results. Results ground 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 sixer drops of each of the four test acid solutions to the four test tubes.
bring ining 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 not e pH level. Add another three, then six, th! en another 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:
