A novel procedure for the determination of ethanol in distilled beverages using smartphone-based digital images is proposed. It pioneering exploits influence concentration on radiation absorption by phenolphthalein alkaline medium. This effect attributed to low dielectric constant comparison with water, which affects resonance structures phthaleins and closure lactone ring. The color intensity was measured converted RGB values a smartphone free application (App). Aiming at portability, an...
