Blood Electrolyte Levels and Anion Gap

NHS Blood Electrolyte Levels and Anion Gap and Tests

Wikipedia: Electrolyte

• Anion a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis. The opposite of cation.

• Cation a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis. The opposite of anion.

• Ion an atom or molecule with a net electric charge due to the loss or gain of one or more electrons:

• pH a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline. The pH is equal to −log c, where c is the hydrogen ion concentration in moles per litre.

• pH in Blood 7.35 to 7.45
