Answer: [H+] = 10^-7.2

Step-by-step explanation:

Given that the PH of the solution = 7.2

Using the formula pH = - log[H+]. To get the H + concentration from the pH, raise both sides by the base of 10. Then we have

10^ - pH = H+. with pH of 7.2,

Thus the answer to this problem is

[H+] = 10^-7.2
