The Home navigation screen provides access to all modules included in the app.

1. The "HCl Dilution" module allows the preparation of a diluted solution from a concentrated acid.
2. The "HCl Concentration" module allows the preparation of a more concentrated solution from diluted acid by the addition of raw or more concentrated acid.
3. The "Neutralization" module allows the calculation of the required quantity of various alkaline to neutralize the given volume of HCl acid to a pH of 7.
4. The "Neutralization - Partial" module allows the calculation of the required quantity of various alkaline to neutralize the given volume of HCl acid to a reduced concentration.
5. The "Concentration vs pH" module allows the calculation of the pH value corresponding to a given concentration and vise versa, calculates the concentration value corresponding to a desired pH value.
6. The "Solution Preparation" module allows the calculation of the required acid volume from a given concentration to mix a solution with a given "Molarity/Normality"
7. The "HCl Properties" screen gives a general information related to the product phisycal and chemical properties.
8. The "First Aid" screen provide guidance to basic first aid steps taken when exposed to uncontrolled HCl environment.
9. The "Units" screen allows user to set preferred calculation units
10. The "Help" screen allow access to this help document
11. The "About HCl Acid" screen allows access to developer website, App rating and reporting bugs.
