Answer:
0.002M
Step-by-step explanation:
2.7= -log(H^+)
-2.7=log(H^+)
10^-2.7 M=H^+
0.0002M=H^+
The stomach has an acidic fluid that is an important part of the digestive juices. The pH of 2.7 in the stomach is close to a 0.002M concentration of hydrogen.
What is pH?
pH measures the concentration of the hydronium and the hydrogen ions in the solution. pH is calculated as:
pH = -log (H⁺)
Here, pH = 2.7
Substituting values:
2.7 = -log (H⁺)
-2.7 = log (H⁺)
H⁺ = 10⁻²⁷ M
H⁺ = 0.0002M
Therefore, 0.002M is the concentration of hydrogen.
