pH of KOH Online Calculate pH and pOH of Potassium Hydroxide
WebOct 22, 2024 · Thus, pH = 14 - 4.74 = 9.26. CASE TWO: after addition of 12.5 mL of HBr. Number of moles of H^+ present= (The initial concentration of H^+) × ( addition of 12.5 mL of HBr) = 0.220 × 12.5 × 10^-3= 2.7 × 1O^-3 mol. Number of moles of C5H5N present = 25 × 10^-3 × 0.220. = 5.5 × 10^-3 mol. Therefore at equilibrium; WebDec 10, 2024 · Given that –. pH = 12.5 ; We know that –. pH + pOH = 14; Then – Now the number of moles of KOH need to ensure that concentration of Hydroxide anions is equal to – siaf honiara facebook
