Refractive Index Method For Measurement Of Alcoholic Strength Of Local Alcoholic Beverages (Arekes) Using Prism Spectrometer

Abstract

Several Methods Were Developed To Determine The Refractive Index Of Different Solutions. In This Research, The Refractive Index Of Various Local Beverages (Areke) And Alcoholic Strength Were Determined Using A Prism Spectrometer By Measuring The Angle Of Minimum Deviation Using Laser Light Of Different Wavelengths. The Refractive Index Of Dagim,Cereal Yegibto And Yetenaadam And Yenechshinkurt Were In The Range Of (1.3540 . The Minimum Refractive Index Was Recorded For Cereal Areke (1.3540 And The Maximum For Dagim Areke ( Using Red Diode Laser (650nm). The Alcoholic Strength Of Areke Collected From Different Parts Of Ethiopia Was Analyzed By Adopting The Method Of Determination Of Reactive Index Of Ethanol Solution. The Alcohol Strength Of ?��?Areke?��? Was Determined By Using Regression Equation Using Origin Software. The Alco
