WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution. WebMar 6, 2024 · Calculate pH by pH + pOH = 14 According to the theory 1, OH - concentration is 0.1 mol dm -3 Now, you can use the equation 3 to calculate pOH with known OH - concentration. pOH = -log 10 [OH -(aq)] pOH = -log 10 [0.1] pOH = 1 Now, use the equation 3 to find the pH pH + pOH = 14 pH + 1 = 14 pH = 13 pH of 0.1 mol dm-3 KOH solution is 13. …

WebA solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base. Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated. WebApr 30, 2014 · NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. Since pH + pOH = 14 We can calculate the pH to be 13.
