Question

Calculate the hydrogen ion concentration in the biological fluids whose pH is Human stomach fluid, 1.2.

Answer 1

[H⁺] of human stomach fluid

pH = 1.2 or log\(\bigg[\frac{1}{H^+}\bigg]\) = 1.2

\(\bigg[\frac{1}{H^+}\bigg]\) = Antilog 1.2 or [H⁺] = Antilog (-1.2)

[H⁺] = Antilog \((\bar8.62)\) = 4.168 x 10^-8 M
