when enough base has been added to neutralize the acid.
Because you know the concentration of the base you are
using, the amount of acid in your test sample can be easily
calculated. The calculation is as follows:
(Normality of Base) × (Volume of Base) = (Normality of
Unknown) × (Volume of Unknown)
Because the calculations are just the arithmetic of converting
molarity to grams per liter, I have designed the procedure
below to take that into account, and use just a one-time
multiplication.
Supplies
150 ml beaker
1 glass stirring rod
110 ml syringe
1 cup distilled water
1 container of 0.1N sodium hydroxide solution
Procedure
Wear safety glasses.
Use the clean syringe to measure 5 ml of wine must and
transfer it into the beaker.
Clean the syringe and then rinse with the distilled water.
