PH is a parameter that tests the acidity or basicity of a substance or a solution. In this case, the formula to be followed is pH = - log[H+]. To get the H + concentration from the pH, we manipulate the equation by raising both sides by the base of 10. Thus, 10^ - pH = H+. with pH of 7.2, thus the answer to this problem is C [H+] = 10^-7.2
