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

Explanation

To calculate the hydrogen ion concentration in various biological fluids based on their pH values, we can use the formula:

\[ \text{pH} = -\log[H^+] \]

From this, we can derive the hydrogen ion concentration \([H^+]\) as follows:
