An ,ion, (/ ˈ aɪ ɒ n,-ən /) is a particle, atom or molecule with a net electrical charge.. The charge of the electron is considered negative by convention. The negative charge of an ,ion is equal, and opposite to charged proton(s) considered positive by convention. The net charge of an ,ion, is non-zero due to its total number of electrons being unequal to its total number of protons.

pH Buffers in the Blood
pH Buffers in the Blood

This optimal buffering occurs when the ,pH, is within approximately 1 ,pH, unit from the pK value for the buffering system, i.e., when the ,pH, is between 5.1 and 7.1. However, the normal blood ,pH, of 7.,4, is outside the optimal buffering range; therefore, the addition of protons to the blood due to strenuous exercise may be too great for the buffer alone to effectively control the ,pH, of the blood.
