Titrant - Study guides, Class notes & Summaries

How does Volume Decrease Affect Equilibrium? - Equilibrium will shift toward the side with the fewest gas molecules. How does Volume Increase affect Equilibrium? - Equilibrium will shift the reaction left How will an increase in temperature affect the equilibrium of a solution with a -delta H? - Reaction is Exothermic so the reaction will shift left How will an increase in temperature affect the equilibrium of a solution with a +delta H? - Reaction is Endothermic so the reac...

CHEM 210 Midterm 2 Exam Questions and Answers All Correct Identify the equivalence point on the titration curve. Define the end point of a titration. - Answer-The equivalence point of a titration is reached when the moles of titrant added are stoichiometrically equal to the moles of analyte present in solution. This is observed on the titration curve as the point in the center of the steepest part of the curve, which correlates to the greatest concentration (pH) change per volume of add...
