Determining the Equivalent Mass and Dissociation Constant of an Unknown Weak Acid by Titrimetry Adam Capriola CHM 1122 Section 155 February 28, 2007 Unknown Label: T Introduction Acids are substances that donate hydrogen ions and bases are substances that accept hydrogen ions. Results Identification code of weak unknown acid Mass of unknown acid, g Final buret reading, mL Initial buret reading, mL Volume of NaOH solution required, mL Concentration of NaOH solution used, M T . 167 1. 7 . 5 1. 2 . 0 x 10-1 Mass of unknown acid requiring 25 mL of NaOH solution for titration, g Mass of unknown acid.

The Ka and Molar Mass of a Monoprotic Weak Acid Chemistry Lab 152 Professor: James Giles November 7, 2012 Abstract: The purpose of this experiment was to determine the pKa, Ka, and molar mass of an unknown acid (.The pKa was found to be . 8, the Ka was found to be . 18 x 10 -4, and the molar mass was found to be 17. g/mol. Introduction Acids differ considerable as to their strength.

and Dissociation Constant of an Unknown Weak Acid by Titrimetry. Acids and bases react with each other by transferring hydrogen ions. To find the mass of unknown acid needed using 25 mL of NaOH solution, I used a proportion.

Determining the Equivalent Mass and Dissociation Constant of an Unknown Weak Acid by Titrimetry. 1361 Words Nov 16th, 2012 6 Pages. One way to distinguish an acid is by its equivalent mass, which is the number of grams of the acid needed to transfer one mole of hydrogen ion to a base. The proportion was . 167 g, 1. 2 mL x, 2. 0 mL, with x equaling the mass of unknown acid needed.

2) How would the error you described in (1) affect the calculated equivalent mass of the unknown acid? briefly explain. 3) How would the error you described in (1) affect the calculated Ka of the unknown acid? briefly explain. Suppose that a stuent peforming this experiment mistakenly calibrated the PH meter using PH6 buffer, instead of PH7 buffer. as a result, all PH meter readings were too low. 1) Would this procedural error have affected the calculated equivalent mass of the unknown aid? briefly explain

The equivalent mass of an acid or base is also equal to the mass of the . Looking at the table in the lab book, the acid with the closest pKa to my calculated pKa is trans-crotonic

The equivalent mass of an acid or base is also equal to the mass of the acid or base titrated divided by the number of equivalents of the acid or base. Acid strength is measured by how much it dissociates. The inflection point found by graphing is the equivalence point, and at half that volume is the half-equivalence point. Looking at the table in the lab book, the acid with the closest pKa to my calculated pKa is trans-crotonic. It has a pKa of . 9 while my calculated pKa was .
