The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH = -log x where x
represents the concentration of the hydrogen ions in the solution in moles per liter. Find the hydrogen ion concentration if the pH=4.4.
A. 3.98×10^4
B. 3.98x10^-5
C. 2.51 x 10^-4
D. 2.51 x 10^-5
