When a strong acid such as HCl is added to the carbonic acid buffer system, . When a strong acid such as HCl is added to the carbonic acid buffer system, . hydrochloric acid is neutralized by sodium hydroxide the blood plasma pH is reduced carbonic acid is converted into bicarbonate more carbonic acid is formed

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
