Controlled deals of whiz 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 thou 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) + CH! 3COO- (aq) + H2O (l) The titration of NaOH with KHP will list 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 / hoagy mass of KHP = Mass of KHP recorded / 204.22g/mol The volume of NaOH will be determined by reading the burette : V(mL) NaOH = final buret reading - Initial buret reading The reaction between NaOH and KHP is...If you want to get a to the full essay, distinguish it on our website: OrderCustomPaper.com
