<u>We are provided that</u> –

<u>Applying identity</u> –

$\qquad$ $\twoheadrightarrow\bf(w-10x) (w+10x)$

$\qquad$ $\twoheadrightarrow\bf w^2 - (10x)^2$

$\qquad$ $\twoheadrightarrow\bf w^2 -100 x^2$

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
