(1) In todays lab we will: groom a thorough understanding of the concepts involved with titrations, become versatile with the laboratory techniques involved in titrations, use titration to standardize a sodium hydrated oxide solution, and standardized solution will be saved for use in the next experiment.
(2) One of our objectives in this experiment is to standardize a solution of sodium hydroxide. The margin standardize means to determine a precise and accurate concentration. To standardize the NaOH(aq) solution we will perform a titration employ KHP as our primary standard. We call this an acidbase titration because the reception that is taking place during the titration is between an acid and a base. To standardize the NaOH(aq) solution we will perform a titration using KHP as our primary standard. We call this an acidbase titration because the reaction that is taking place during the titration is between an acid and a base.
(3) 1 50-mL burette (check out from stockroom)
250-mL Erlenmeyer flasks? 500-mL storage flask (round bottom) with stopper
Approximately 6 M NaOH(aq) Solid potassium hydrogen phthalate (KHC8H4O4)
Care in force(p)y budge the KHP to a 250-mL Erlenmeyer flask.
The flask does not need to be dry, as wide as it is clean and has been rinsed with deionized water. Add about speed of light mL of distilled water and swirl the solution to dissolve the KHP. Carefully transfer the KHP to a 250-mL Erlenmeyer flask. The flask does not need to be dry, as long as it is clean and has been rinsed with deionized water. Add about 100 mL of distilled water and swirl the solution to dissolve the KHP. reprise twice more.
(4) According to my results my average molarity for sodium hydroxide was 0.1799. My first trial i got .1805, second trial i obtained a molarity of 17.48 and my final trial i obtained .1842. During the prelab we careful that the approximate mass of KHP was .800g. My results...If you want to get a full essay, order it on our website: Ordercustompaper.com
