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.
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.
To determine the [H+], you can use the negative logarithm of the hydrogen ion concentration. The formula for pH is pH = -log[H+].
Given that the blood plasma pH is 6.72, we can calculate the [H+] using the formula:
[H+] = 10^(-pH)
Plugging in the value for pH:
[H+] = 10^(-6.72)
Calculating this using a calculator or Python:
[H+] ≈ 2.26 x 10^(-7) mol/L
Therefore, the [H+] of the blood plasma is approximately 2.26 x 10^(-7) mol/L.
To calculate the [H+], we can use the formula:
[H+] = 10^(-pH)
Substituting the given pH value into the formula:
[H+] = 10^(-6.72)
Calculating the value:
[H+] ≈ 2.51 x 10^(-7) mol/L
Therefore, the [H+] of the blood plasma is approximately 2.51 x 10^(-7) mol/L (two significant figures).
