WebbClick here👆to get an answer to your question ️ The pH of 10^-3M NH4 OH ( Kb = 10^-5 ) is: WebbGo through the simple and easy guidelines on how to measure pH value. Know the concentration of hydrogen ions in the solution. Calculate the pH by using the pH to H + formula i.e pH=-log [H +] You can also calculate the pOH and the concentration of hydroxide ions. The other way to know pOH is subtract 14 from pH value.
WebbAnswer (1 of 2): RbOH is a strong base which complete dissociates to give OH⁻ ions. Hence, [OH⁻] = [RbOH]ₒ = 1.0 × 10⁻³ M pOH = -log[OH⁻] = -log(1.0 × 10⁻³) = 3 pH = pKw - pH = 14 - 3 = 11 Webb24 okt. 2013 · Since NaOH is a base, hence we will first calculate its pOH i.e. the negative logarithm of hydroxyl ion concentration and then calculate the pH using the expression. …
