稀釋定理(英語:law of dilution)是威廉·奧斯特瓦爾德提出的一個關於離解常數與弱電解質的離解度之間的關係。 K p = c ( K + ) ⋅ c ( A − ) c ( KA ) = α 2 1 − α ⋅ c 0 {\displaystyle K_{p}={\frac {c{\ce {(K^+)}}\cdot c{\ce {(A^{-})}}}{c{\ce {(KA)}}}}={\frac {\alpha ^{2}}{1-\alpha }}\cdot c_{0}} K p {\displaystyle K_{p}} 質子遷移常數 α {\displaystyle \alpha } 離解度(或質子遷移度) c ( A − ) {\displaystyle c{\ce {(A^{-})}}} 陰離子濃度 c ( K + ) {\displaystyle c{\ce {(K^+)}}} 陽離子濃度 c 0 {\displaystyle c_{0}} 總濃度 c ( KA ) {\displaystyle c{\ce {(KA)}}} 對應電解質濃度 如果考慮電導率,則有以下關係: Λ c 2 ( Λ 0 − Λ c ) Λ 0 ⋅ c = K c {\displaystyle {\frac {\Lambda _{c}^{2}}{(\Lambda _{0}-\Lambda _{c})\Lambda _{0}}}\cdot c=K_{c}} Kc 離解常數 Λ c {\displaystyle \Lambda _{c}} 等效電導率 Λ 0 {\displaystyle \Lambda _{0}} 臨界電導率 c 電解質濃度 Remove adsLoading related searches...Wikiwand - on Seamless Wikipedia browsing.
