Extraction Yield (Solid)
Compute the yield of a solid-liquid extraction, Y = (extract mass / sample mass)·100%, the fraction of raw material extracted by the solvent. It is used in processes such as the extraction of oils, caffeine, pectin, dyes and bioactive compounds from plant matrices. The yield assesses extraction efficiency and guides the optimization of solvent, temperature, time and solid-liquid ratio. Enter the extract mass and the sample mass.

Rendimento de extração (sólido)
Na extração sólido-líquido, um solvente é posto em contato com uma matriz vegetal ou animal para 'arrancar' compostos de interesse — óleos de sementes, cafeína do café, pectina da casca de frutas cítricas, corantes (urucum, açafrão), antioxidantes, óleos essenciais, princípios ativos. O rendimento R = (massa de extrato / massa de amostra)·100% mede quanto da matéria-prima foi efetivamente extraído. É a métrica central para otimizar o processo: testa-se o efeito do tipo de solvente (polaridade casando com o composto-alvo), da temperatura (mais quente extrai mais, mas pode degradar termolábeis), do tempo de contato, da razão sólido-líquido e da granulometria (moer mais aumenta a área de contato). Técnicas modernas — extração assistida por ultrassom, micro-ondas, fluido supercrítico (CO₂) — buscam maior rendimento com menos solvente e menor degradação. Cuidado: rendimento alto não basta — também importam a seletividade (não arrastar impurezas) e a qualidade do extrato. Informe a massa de extrato e a massa de amostra.

Distribution Coefficient (Extraction)
Compute the distribution (or partition) coefficient of a liquid-liquid extraction, KD = concentration in the extract / concentration in the raffinate, the ratio of how the solute distributes between the two immiscible phases at equilibrium. A high KD means the solvent extracts the solute well, requiring fewer stages and less solvent. It is the central parameter of extractor design and solvent choice. Enter the extract and raffinate concentrations.
Chemical Reaction Yield
Compute a chemical reaction's yield, Y = (actual mass obtained / theoretical mass)·100%, comparing what was actually produced with the maximum predicted by stoichiometry. Real reactions rarely reach 100%: there are incomplete reactions, side reactions, purification losses. Yield is the efficiency indicator that separates paper chemistry from lab and industrial chemistry. Enter the actual mass obtained and the theoretical mass.
