Task: Text Categorization
Input (English): One form of it uses a reaction between iodine and sulfur dioxide to measure the presence of water, and is named for Fischer. A conductometric version of performing it requires the temperature to be constant, while the redox variety of it uses a potentiometer. This process is generally represented by a sigmoid curves, whose midpoint usually gives the equivalence point. For 10 points, identify this method used to find the concentration of an unknown sample, notably used with acids and bases.
Output (English): Science
