Calculate the ph of this solution. round to the nearest hundredth. poh = 3.45 ph =
maks197457 [2]

The potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.

What is pH of solution?

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

It is expressed as;

pH = -log[ H⁺ ]

Also,

pH + pOH = 14

Given that;

  • pOH = 3.45
  • pH = ?

We simply substitute our values into the expression above.

pH + pOH = 14

pH + 3.45 = 14

pH = 14 - 3.45

pH = 10.55

Therefore, the potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.
