Answer:

Hydrogen concentration = 7.94×10^-3 M

Explanation:

from potenz Hydrogen ( pH ) definition

pH = -log[H+]

2.1 = -log[H+]

2.1/-log = -log[H+]/-log

10^-2.1 = [H+]

[H+] = 7.94×10^-3M

The correct answer is Hydrogen concentration = 7.94×10^-3 M

What is hydrogen concentration?

  • The hydrogen ion concentration generally found in many chemical and biological systems are very small, and often in the range of 10 -2 to 10 -12 mol L -1.
  • pH = -log[H+]
  • 2.1 = -log[H+]
  • 2.1/-log = -log[H+]/-log
  • 10^-2.1 = [H+]
  • [H+] = 7.94×10^-3M
