The equation for the ph of a substance is pH=-log[H*], where H+ is the concentration of hydrogen ions. What is the approximate pH of a solution whose hydrogen ion concentration is 2x10^-9

Respuesta :

Catya
Just put the formula into the calculator with H+ = 2×10^-9.

pH = - Log(2×10^-9)
pH = 8.70

Answer:

The approximate pH of a solution 8.69.

Step-by-step explanation:

The pH of the solution is defined as negative logarithm of [tex]H^+[/tex] ion concentration in the solution.

[tex]pH=-\log[H^+][/tex]

[tex]pH=-\log[2\times 10^{-9}]=8.69[/tex]

The approximate pH of a solution 8.69.
