Acid base titration lab answers chegg. 9 ml 2 8. This result is expected because a combination of strong acids and strong bases should result in a neutral at the equivalence point. i also am unsure how to calculate the molarity Question: Acid-Base Titration Virtual Lab Introduction In chemistry laboratory, it is sometimes necessary to experimentally determine the concentration of an unknown acid or base solution. O (net) These reactions are -prepare diltute solution of NaOH and standardize it by using oxalic acid -Titrate all 3 flask -end point of titration will be determined when clear solution turns to a faint pink color -pH of clear oxalic acid is<7-pH of faint pink endpoint: pH8-pH of dark pink overshot: >8-2 drops of phenolphthalein in erlenmeyer flask with around .

To become familiar with volumetric analytical techniques 3. (Discard in waste container) (B) Titration of an Acid of unknown concentration with the Standardized NaOH In the second titration, the same NaOH titrant (now of known concentration) is used to titrate an analyte containing an unknown concentration of sulfuric acid: H2SO4(a) + 2 NaOH(aq) → Na2SO4(aq) + 2 H,00 (overall) но" + OH H2O + H. Final NaOH level in buret 39. 05 Volume of base used (mL) (V final - Vinitial) Calculations 1. In the lab, a titration is when a solution of unknown concentration is reacted with a solution of known concentration. i was hoping for some guidance regarding question 1-3.
