WebMay 8, 2015 · The difference between the strong cations and the strong anions (the positives and the negatives) in “balanced fluids” is 24-28. In plasma, the actual difference between the sodium (Na) (142 mEq/L) and chloride (Cl) (103 mEq/L) is approximately 39. WebThe strong ion difference is the difference between negatively and positively charged strong ions. Since Na + and Cl – are the most abundant strong ions, it is relatively simple to calculate the SID (inorganic) from Na + and Cl –, as follows: SID(inorganic) = Na+ + H+ = Cl– + OH–, rearranging this yields: SID(inorganic) = Na+ – Cl–corr = OH–– H+.
