## Acid – Base Titration

Acid – Base Titration. Prelab question. M A x #H x V A = M B x #OH x V B M A = 6 M, #H = 2, V A = ? M B = 0.5 M, #OH = 1, V B = 0.5 L (6 M)(2)(V A ) = (0.5 M)(1)(0.5 L) V A = (0.5 M)(1)(0.5 L) / (6 M)(2) V A = 0.25 mol / 12 M = 0.0208 L = 2 0.8 mL.

## Balancing Redox Equations in Acidic Conditions

Balancing Redox Equations in Acidic Conditions. Take the reaction between potassium permanganate （ KMnO 4 ) and sodium sulfite (NaSO 3 ) 7 steps are required to balance the full ionic equation from 2 separate half equations ( oxidation & reduction ). Step 1.

## X- + H 3 O + HX + H 2 O

X- + H 3 O + HX + H 2 O. Add strong acid. Use Ka, [HX] & to calculate [H + ]. Recalculate [HX] & [X - ]. Buffer HX & X -. pH. Add strong base. HX + OH-  X- + H 2 O. Equilibrium calculation Use Henderson-Hasselbalch. Stoichiometric calculation.

## Notes 16.3

Notes 16.3. Acid/Base Titration. Acid-Base Titrations. A neutralization reaction is when there is equal amounts of H+ and OH- available for a reaction and a neutral solution (pH=7) will result. To analyze the acid/base content of a solution, titrations are often performed

## Acid-Base Titrations

Acid-Base Titrations. progressive addition of one reactant to another in measured volumes until an endpoint is reached. equivalence point (mL) is when the mole ratio is exactly satisfied, volume used for stoichiometry is shown by an indicator which changes color at the endpoint (pH).

## Titrations MATH!!!!

Titrations MATH!!!!. weak base. indicator. K a. strong acid. K b. [H + ]. equivalence point. To Find the Equivalence Point. (ex) When titrating 50.0mL of 0.48M HCN with 0.75M NaOH , what volume of base must be added to reach the equivalence point?. Strong Acid with Strong Base.

## Volumetric analysis

Volumetric analysis. Chemistry 321, Summer 2014. Volumetric analysis involves titrations. A titration is the use of a known concentration reagent to determine the concentration of the analyte . Typically, a buret is used to dispense the volume of the reagent. Titration is a good technique.

## pH and Titration

pH and Titration. Purpose. To “titrate” means to mix chemicals for the purpose of measuring one of the chemicals Acid/ Base titrations are done by mixing acids and bases. One is slowly added to the other until and “endpoint” is reached.
