Calculate the hydrogen ion concentration in the following biological fluids whose pH are given below: (a) Human muscle-fluid, 6.83 (b) Human stomach, 1.2 (c) Human bloody 7.38 (d) Human saliva, 6.4.  

Answer:

(a) \[[{{H}^{+}}]=Anitlog\,[-pH]\] \[=\text{Antilog}\,[-6.83]\] \[=1.479\times {{10}^{-7}}M\] (b) \[[{{H}^{+}}]\]= Antilog [-1.2] = 0.063 M (c) \[[{{H}^{+}}]=Antilog[-7.38]\] \[=4.168\times {{10}^{-8}}M\] (d) \[[{{H}^{+}}]=Antilog[-6.4]\] \[=3.98\times {{10}^{-7}}M\]
