equation to find pH using the H+

pH=-log(H+)

equation to find H+ using pH

H+=10^-pH

equation to find OH- using pOH

OH-=10^-pOH

equation to find pOH using OH-

pOH=-log(OH-)

H30 is another term for

H+

H+ is another term for

H3O

a .10 M solution of an acid has a pH of 2.74. Is the acidic weak or strong.

The acid is weak since 1 pH doesn’t equal 2.74
