Question

Three white wine brands, D, M, and B were tested for tartaric acid (FW=150.09) content. Tartaric acid has two acidic hydrogens. The allowable tartaric acid content in wine is in between 0.5 g to 10 g per liter. The wine is considered to be unstable with too much tartaric acid and content.

 

However, since the bottle storing NaOH was left ajar for over two weeks, this was standardized again with KHP (FW=204.22) thrice with the following masses of KHP and their respective volumes, shown in the table 1.

 

Table 1.

Preparation of the wine sample: 50.00 mL of each wine (d=1.75 g/mL) was diluted to 250.0 mL with water and a 50.00 mL aliquot was titrated with the NaOH, with results in table 2.
