Step 4

We have established that your compound is a hydrophilic acid. Now we need to know how acidic your analyte is. Please choose a button below to move to the next step.

Is your compound a . or a .?


Weak acids – compounds that go through the transition from a negatively charged state to a neutral state within a pH range from 2 to 7 (pKa > 3).

Strong acids – compounds which are significantly ionized in solutions at a pH of 3 (pKa < 3).
