hey hi mate

wassup

answer is 4

explanation To calculate the pH of a solution, use the equation

p

H

=

−

log

[

H

3

O

+

]

Since we are given the hydronium ion (

H

3

O

+

) concentration of the solution, we can plug this value into the formula.

p

H

=

−

log

p

H

=

4

The pH of this solution is 4.

Added notes:

p

H

=

p

H

3

O

+

because hydrogen ions attach to water molecules for form hydronium ions.

Some other key things to remember for pH calculations include:

pH + pOH = 14

pH = -log[

pOH = -log[
