Using the talking-aloud technique, the students were required to calculate the concentration of hydrochloric acid used in a titration with NaOH after having performed the titration themselves. Students were met individually and their verbalization audiotaped. After making this calculation, each student ...

Strong Acid Titration Curve At the beginning, the solution has a low pH and climbs as the strong base is added. As the solution nears the point where all of the H+are neutralized, the pH rises sharply and then levels out again as the solution becomes more basic as more OH- ions are ...

A total of 3.55 x 10-3moles of NaOH were put into the solution.Since the titration reached the equivalence point at this time, that means thatthe number of moles of NaOH added would have to be the same as the number of moles of propanoic acid in the original solution.If we divide3.55...
