If I add hydronium ion (H 3 O+) or Hydrogen Ions (H+) to a solution, assuming no other complications, what will happen to the pH reading? And
what will happen to a pOH reading?

What is the formula that this ionic compounds could form sr2+p3-o2-

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
