Quadratic - Calculates answers to quadratics.
Version: 2.2Quadratic is a small and simple software application that calculates the answers to the quadratic formula.
Operating System: Mac OS X
In addition, it calculates pH in strong acid and weak acid dissociations given the pKa or Ka and the concentration of the original acid.
All you have to do is just put in the numbers, the only part that is a bit tricky is if you need to do scientific notation, for example the picture below and the picture above are equivalent and the concentrations of the reactants are both the same. Many times while calculating pH you'll have to input numbers like 7 X 10^-30. OS X makes it easy to input this by replacing the X10^ by the letter 'e'. After that just click calculate and you're done.
