PURPOSE AND method Clearly state the exercise of this lab. Explain how this is accomplished in this experiment. What calculations do you need to perform? What measurements lead be make? [Do not provide experimental details here]. How do you go f rom calculated/measured values to accomplishing stated drive? (4 pts) The purpose of this lab is to determine the exact concentration of an vague acetic vitriolic solution. Titrations for two different receptions will be performed.

Controlled deals of nonpareil reagent are added to a flask containing the other reagent until the equating point of the reaction is reached, one between sodium hydrated oxide (NaOH) and kelvin hydrogen phthalate (KHP) and the other between NaOH and acetic acid (CH3COOH). NaOH (aq) + KHP (aq) › Na+ (aq) + K + (aq) + P2- (aq) + H2O (l) NaOH (aq) + CH3COOH (aq) › Na+ (aq) + CH3COO- (aq) + H2O (l) The titration of NaOH with KHP will! localize the concentration of the NaOH provided. KHP will be weighed and its mass will be enter. The moles of KHP will be calculated: Moles KHP = Mass KHP recorded / hoagie mass of KHP = Mass of KHP recorded / 204.22g/mol The volume of NaOH will be determined by reading the burette : V(mL) NaOH = last(a) buret reading - Initial buret reading The reaction between NaOH and KHP is...If you want to get a to the full essay, format it on our website: OrderCustomPaper.com
