Acide eg: $HCOOH$, $CH_3COOH$ , $HF$, $HClO_2$ ..
Base eg: $NaOH$, $KOH$, ...
To have a reliable result we will choose (approximate formulas used, see → here ):
A molarity of the titrated acid of between 0.05 mol/L and 0.2 mol/L
- As molarity of the titrating base 0.05 mol/L or 0.1 mol/L or 0.2 mol/L
- As volume of the acid 10 mL or 20 mL or 25 mL
a weak acid of $pK_a$ between 2 and 9
