Molar fractions
Vaxa Software brings you a new tool for calculating acid-base equilibria.
Solve your problems instantly.
ABEW can calculate pH, concentrations, equilibrium constants, degree of dissociation and volumes for 34 types of calculation of acid-base equilibria.
Strong and weak , monoprotic, diprotic and triprotic acids.
We can plot graphics for all equilibria, reaching a higher level of understanding.
At home or in the classroom, ABEW is suitable both for learning and for teaching.
Easy and fast to use - User's manual in PDF format.

26 types of graphics:
pH, concentrations, degree of dissociation, equilibrium constants, volume...
Data table
Each graph has a data table. Of course we can save and print it.

Notes:
<R> Only available in the registered version.
( * ) All triprotic and diprotic acids have the option "First dissociation is complete" . This option counts as a new type of calculation.
