By the conductometric method, the dependence of the specific electrical conductivity (χ) of five apple juice samples on the volume fraction (φ) of apple juice in a solution with distilled water. The dependence χ in the range φ from 0 to 1 acquires a power-law character (the correlation coefficient is close to 1), since a significant part of the mineral composition of apple juices consists of various organic acids. The technique fully complies with the principles of “green” chemistry, since the “waste” is apple juice diluted with distilled water.
