You may then use this curve to locate the midpoint with the titration. Within the midpoint of your titration of a weak acid with a strong base, (pH = pK_ a ). As a result we will use the midpoint of the titration curve to confirm the value of pKa for your mysterious acid.

We assist and repair your measurement gear by means of its overall existence-cycle, from installation to preventive upkeep and calibration to equipment mend.

Pure water has a pH of 7 and is considered “neutral” mainly because it has neither acidic nor essential features.

In unique problems (aqueous solutions at space temperature), we could determine a beneficial romance in between pH and pOH:

Dividing this destructive mass via the molar mass offers us a negative amount of moles, leading to an imaginary pH.
