*2.5. Free Acidity and pH Value*

Ten grams of honey were dissolved in 75 mL of carbon dioxide-free water. Using a magnetic stirrer and a pH meter, the pH value was determined. The volumetric method was then used to determine the acidity of honey. With 0.1 mol/dm<sup>3</sup> of NaOH, the sample solution was titrated to pH 8.30. Honey's acidity is expressed in milliequivalents per kilogram (mEq/kg).
