Signature: Note: either sections of this report moldiness be typed Total Points = 60 pts (5 pts notebook, 55 pts template) Notebook Pages: Your notebook pages go out be stratified for general organization and completeness (Can your TA easily find and rake the data he/she is looking at for?) PURPOSE AND system Clearly state the exercise of this lab. Explain how this is accomplished in this experiment. What calculations do you need to perform? What measurements depart be make? [Do not provide experimental details her e]. How do you go from calculated/measured values to accomplishing stated exercise? (4 pts) The purpose of this lab is to determine the exact concentration of an vague acetic vitriolic solution. Titrations for two different answers will be performed.

Controlled deals of whizz 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 special K 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) â €º Na+ (aq) + CH3COO- (aq) + H2O (l) The tit! ration of NaOH with KHP will draw 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 / poor boy mass of KHP = Mass of KHP recorded / 204.22g/mol The volume of NaOH will be determined by reading the burette : V(mL) NaOH = net buret reading - Initial buret reading The reaction between NaOH and KHP is...If you want to get a to the full essay, golf-club it on our website: OrderCustomPaper.com
