Quadratic

Quadratic is a software application that provides users with a simple and easy-to-use way to calculate the quadratic formula. What's more, it also allows users to calculate the pH in strong acid and weak acid dissociations, given the pKa or Ka, and the initial acid concentration. To use it, all that is required is inputting the numbers. The only slightly complicated part may be inputting scientific notation. For example, the concentrations in the two pictures below are the same. Often, while calculating pH, users may need to input numbers like 7 x 10^-30. However, on OS X, this is made easy by simply replacing "x10^" with the letter "e". Once the desired numbers have been inputted, users can simply click "calculate", and the task is done!
