Chemical Formulas and Chemical Equations Purpose: To study different types of chemic equations and to conclude if a reaction overtakes when two compounds atomic number 18 combined. When reactions occur you should and hence be able to predict the products which are formed. Procedures for serial publication A-E serial publication A: quaternion streak solutions and four reagents are added together making 16 reactions. You note the appearance of both the solutions before and after the reactions and to a fault noting if precipitates are formed. Results put in in data tables. Series B: allure spues of reagent, 2M HCl, is added to apiece of the three ravel solutions and one test unattackable noting the results. Results rear in data tables. Series C: One dusk 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 flipper more drops of ammonia solution to to for individually one one of the test solutions, aggregate contents and record results. Finally, you add five more drops of 6M NH (aq) to each solution, mix and record results. Results set up 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 half a dozen drops of each of the four test acid solutions to the four test tubes.
transmiting 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, s tir, and note pH level. Add another three, ! then six, then 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:
