Abstract

This study aims to identify the electrolyte properties of various imported fruits through electrolysis experiments. A quantitative approach was used by measuring the presence of gas bubbles formed on electrodes as an indicator of electrolyte strength. Samples included apples, pears, grapes, lemons, mandarins, strawberries, cherries, kiwis, blueberries, and dates. The results showed that all tested fruit extracts exhibited electrolyte properties due to the presence of organic acids (such as citric, malic, and tartaric acids) and minerals that can ionize into free ions. Apples showed the strongest electrolyte activity, followed by pears, grapes, lemons, and mandarins, while cherries, kiwis, blueberries, and dates showed weaker conductivity. Electrolyte strength was influenced by factors such as ion concentration, acid type, and mineral content. These findings suggest that fruit extracts, especially those with higher acidity levels, have the potential to act as natural electrolytes and serve as an alternative source of environmentally friendly electrical energy.

Abstract

This study was conducted to examine the polarity and electrolyte properties of several types of imported fruit that are increasingly consumed by the Indonesian people after the Covid-19 pandemic. The method used was a laboratory experiment conducted using three types of polar-nonpolar solvents and a simple multimeter-based electrolyte circuit to measure conductivity by testing extracts of ten imported fruits (melon, dragon fruit, strawberry, kiwi, pomegranate, grapes, cherries, lemon peel, blueberries, and dates). The polarity test was carried out using three different solvents (water, vinegar, and cooking oil), while the electrolyte properties were observed with a simple electrical circuit. The results showed that most of the extracts were soluble in water and vinegar, but not in cooking oil, so the majority of the fruit components were polar. Lemon peel and melon peel have semi-polar properties due to their essential oil content. In the electrolyte test, fruits with high acid content (lemon, pomegranate, strawberry) act as strong electrolytes, while fruits with high sugar content (dates, melon) are only classified as weak electrolytes. Other fruits such as grapes, kiwi, and blueberries show moderate electrolyte properties. These findings support basic chemical concepts regarding the relationship between polarity, solubility, and electrical conductivity, and can be utilized in teaching and food technology applications.
