Some Information about luminol
IUPAC name: 5-amino-2,3-dihydro-1,4-phtalazinedione
Molar mass: 177,16 g/mol
Melting point: 319 – 320 °C

Definition: The molar heat of neutralizing represents the quantity of heat given up when a mole of a hydronium ion interacts with a mole of hydroxyl ion in a diluted solution.

INTRUCTIONS ON HOW TO USE IT: This Excel game is to be used as a sort of quiz game in Chemistry and Geology. The file contents two Excel sheets (bottom left of the screen), one for each subject. The user (student) will see several pictures related to these subjects, and in the box underneath he/she will write the word which describes the picture. If it is correct, it will be so announced with a green background. If not, it will be red and the user will be asked to try again.

Objective of the activity is to determine the quality of water samples of different sources using chemical and microbiological indirect methods. The action has planned activities in the laboratory of Chemistry with the determination of the presence of the organic substance, as an indicator of contamination, through the method of Kubel and in the laboratory of Microbiology with the determination of Total Coliforms with MPN method.
