A patient with severe metabolic acidosis has a blood plasma pH of 6.72. What is the [H; 0+] of the blood plasma?

Express your answer to two significant figures and include the appropriate units.

1 answer

To find the [H+] concentration, we can take the negative logarithm of the hydrogen ion concentration.

pH = -log[H+]

To isolate [H+], we can rearrange the equation:

[H+] = 10^(-pH)

[H+] = 10^(-6.72)

[H+] ≈ 1.94 × 10^(-7)

Therefore, the [H+] concentration of the blood plasma is approximately 1.94 × 10^(-7) mol/L.
