WebJun 24, 2024 · Estudos termodinâmicos da solubilidade do KNO3 – parte I. O nitrato de potássio é um sal bastante solúvel em água, sua solubilidade a 25C é de aproximadamente de 40 g do sal/100g de água. Outro fato importante é que sua solubidade é bastante afetada pela temperatura, o que motivou sua escolha para este experimento. WebMay 27, 2016 · Since Δ G ∘ = − R T ln K = Δ H ∘ − T Δ S ∘, we can rearrange and find that ln K = − Δ H ∘ R ( 1 T) + Δ S ∘ R, so a plot of ln K vs 1 T (which is the temperature dependence of solubility) has a slope whose sign is determined only by Δ H ∘.
