I want to prepare 1N succinic acid for 0.1 N NaOH standardisation. I want to use it for of citric acid titration.
Sebastián Finger
As succinic acid is diprotic, 1 N succinic acid for NaOH standarization is 0.5 M (0.5 mol/L). If you want to titrate 0.1 M NaOH it is better to use 0.1 N succinic acid (0.05 M)

Molar Mass Calculation: Determine the molar mass of succinic acid (C4H6O4). The molar mass of succinic acid is approximately 118.09 g/mol. Normality Formula: Recall that normality (N) is defined as the number of equivalents per liter of solution. For succinic acid, which has two acidic protons, the equivalent weight is half of the molar mass. Weight Measurement: Calculate the mass of succinic acid required to make a 1 N solution. Since the equivalent weight is half of the molar mass, for a 1 N solution, you would need 118.09 g/mol / 2 = 59.045 g of succinic acid per liter. Dissolution: Measure 59.045 g of succinic acid using a precise balance, and dissolve it in distilled or deionized water in a volumetric flask. Volume Adjustment: Add water to the flask gradually until you reach just below the 1-liter mark. Finalize Solution: Once the succinic acid has fully dissolved, adjust the water level to the 1-liter mark on the volumetric flask to ensure the correct concentration. Mix Thoroughly: Invert or shake the flask gently to ensure the solution is well-mixed. Storage: Label the solution with its concentration and date of preparation. Store the solution at room temperature away from direct sunlight.
To prepare a 1 N solution of succinic acid for titration, you can follow these steps:
Always use appropriate safety equipment, such as gloves and goggles, when handling chemicals and during preparation.
Take a look at this protocol list; it could assist in understanding and solving the problem.
