<prompt> The normal value of anion gap is:8-16 mEql20-25 meql50 meql75 meql  <response>: Ans. A. 8-16meqlTo achieve electrochemical balance, the number of negatively charged anions should equal the positively charged ions cationsNaK Unmeasured Cations UCCl-HCO3- Unmeasured anions UARearrangingNaK-Cl-HCO3- UA-UC Anion Gap AGBecause normally the total unmeasured anions exceed the unmeasured cations; there is a anion gap.
