NaOH Concentration Determination via Titration

Flashcards for key concepts and procedures in determining NaOH concentration through titration.

Objective of the Practicum

Determining the concentration of sodium hydroxide by titration with a standardized 0.10 mol/L HCl solution.

Materials

Buret, retort stand, buret clamp, 250 mL Erlenmeyer flask, 100 mL graduated cylinder, 10 mL pipette, funnel, white card.

Substances

Phenolphthalein, distilled water, NaOH solution, 0.10 mol/L HCl solution.

Step 1 of the Procedure

Transfer 10 mL of NaOH solution into an Erlenmeyer flask, add a few drops of phenolphthalein, and homogenize.

Step 2 of the Procedure

Fill the buret with the 0.10 mol/L HCl solution.

Step 4 of the Procedure

Titrate until the solution becomes colorless.

Titration Volume

The volume of HCl added to reach the endpoint of the titration.

Calculation Step 1

Calculate the concentration of NaOH in the solution expressed in mol/L.

Calculation Step 2

Calculate the concentration of NaOH in the solution expressed in m/V%.
