Oldószeresek, often translated as solvents, are substances that can dissolve other substances, known as solutes, to form a solution. This process of dissolving is fundamental to many chemical and physical processes. Solvents can be broadly categorized into polar and non-polar types, based on their molecular structure and polarity. Polar solvents, such as water and ethanol, have a partial positive and partial negative charge on different parts of their molecules, which allows them to effectively dissolve polar solutes. Non-polar solvents, like hexane and toluene, have an even distribution of electron density, making them suitable for dissolving non-polar solutes.

The choice of solvent is crucial in many applications, including chemical synthesis, cleaning, and extraction. For example, in organic chemistry, non-polar solvents are often used to dissolve non-polar reactants, while polar solvents are used for polar reactants. In industry, solvents are used in a vast array of processes, from the production of paints and coatings to the extraction of oils and flavors. Environmental and health considerations are also important when selecting and using solvents. Many organic solvents are volatile and can pose fire hazards or health risks if not handled properly. Research into greener, less toxic alternatives is an ongoing area of development. The concept of "like dissolves like" is a general principle that guides solvent selection, suggesting that polar solvents tend to dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.
