What is the range of pH in a solution?

It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. pH is logarithmically and inversely related to the concentration of hydrogen ions in a solution. The pH to H + formula that represents this relation is: pH = -log ([H + ]) The solution is acidic if its pH is less than 7.

What is the relationship between pH and H+?

The pH to H + formula that represents this relation is: The solution is acidic if its pH is less than 7. If the pH is higher than that number, the solution is basic, as known as alkaline. Solutions with a pH equal to 7 are neutral. Apart from the mathematical way of determining pH, you can also use pH indicators.

What is the pH of Baba(OH)2(s)?

Ba(OH)2(s) → Ba2+ +2OH−. So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: [H+][OH−] = 1.0 ×10−14M. [OH−] = 2.0 × 10−1M. [H+] = 5.0 ×10−14M. And then. pH = −log10([H+] = 5.0 × 10−14) = 13.30. Answer link.

What is the pH of barium hydroxide dissociation product?

Barium hydroxide is a strong base for both stages of dissociation: So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: #”pH”=-log_{10}([“H”^+]=5.0xx10^{-14})=13.30#.

What is the concentration of [H+] in a solution of HCl?

HCl is a strong acid that will be full ionized in solution. So, the concentration of [H+] = 0.25 M (or 0.25 mol/L). HCl is a strong acid that will be full ionized in solution.

What is the pH of HCl in Poh?

The pH is the -log [H3O+]; hydronium ion concentration. Since HCl is a strong acid it completely dissociates. Therefore all the H+ protonates water molecules to give H3O+. Its concentration here is high enough to ignore H3O+ contribution from water so the pH is just -log (0.02) = 1.7. pH + pOH = 14 so the pOH is 12.3.
