1. Quantitative Analysis- Titration
Quantitative Analysis determines the quantity (amount) of an element or compound in a sample.
That could mean finding the concentration
of acid in vinegar,
the concentration of ore in a rock,
the amount of aspirin in a tablet,
the concentration of alcohol in wine or
the amount of vitamin C in orange juice.

2. Jenny Suo (L) and Anna Devathasan test the vitamin C content in the Ribena drink at the science lab of Pakuranga College on March 29, 2007 in Auckland, New Zealand.
The maker of Ribena has been fined $217,500 in the Auckland District Court after admitting it mislead customers about the vitamin C content of the blackcurrant drink.
The charges arose from an investigation by teenage Pakuranga College students Anna Devathasan and Jenny Suo into the vitamin C levels of the popular Ribena drink.

3. Acid-Base Titration
To start our titrations, we need a base solution of known concentration (standard solution).
The base needs to be a dry solid that can be weighed accurately. It also needs to dissolve easily in water.
We will use sodium carbonate (Na2CO3).
