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.

(a)
Answer

1.48×10−71.48 \times 10^{-7} M

(b)
Answer

6.31×10−26.31 \times 10^{-2} M

(c)
Answer

4.17×10−84.17 \times 10^{-8} M

(d)
Answer

3.98×10−73.98 \times 10^{-7} M

Explanation

The relationship between pH and hydrogen ion concentration is given by pH=−log⁡[H+]\text{pH} = -\log[H^+]. To find the hydrogen ion concentration from a given pH, we use the inverse relation [H+]=10−pH[H^+] = 10^{-\text{pH}}. We apply this formula to each biological fluid.
