EDTA concentrations for each titrationHomework Answers
Calcium form complex with EDTA in 1:1 stoichiometric ratio.
So, using M1V1 (CaCl2) = M2V2 (EDTA)
For fine 1 : 0.01×10 = M2×9.44
EDTA concentration, M2 = 0.1/9.44 = 0.01 M
For fine 2 : 0.01×10 = M2 ×9.38
EDTA concentration = 0.1/9.38 = 0.01 M
Average concentration of EDTA = (0.01+0.01)/2 = 0.01 M

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
