   5 days ago · The Brønsted–Lowry description of an acid is “a proton donor,” such as hydrochloric acid. Meanwhile, a Brønsted–Lowry base is “a proton acceptor,” such as sodium hydroxide: H C l + N a O H H O + N a C l 2. The Lewis description of an acid is “a lone-pair acceptor.” Meanwhile, a Lewis base is “a lone-pair donor.”

   How do you standardize sodium hydroxide solution?

   • Standardization of 0.1 M sodium hydroxide solution: Weigh about 0.5 g of primary standard potassium hydrogen phthalate (KHP) using an analytical balance and transfer it to a clean, dry Erlenmeyer flask. Add about 50 mL of distilled water to the flask and swirl gently to dissolve the KHP. Add a few drops of phenolphthalein indicator to the solution.

   How do you titrate KHP with sodium hydroxide?

   • Titrate the KHP solution with the 0.1 M sodium hydroxide solution until a pink color is observed. Record the volume of the sodium hydroxide solution used for the titration. Calculation: The molar mass of KHP is 204.22 g/mol. The equation for the reaction between KHP and sodium hydroxide is: KHP + NaOH → NaKP + H2O

   The result is that the pOH scale is the mirror of the pH scale. At 2 5 ∘ C, the sum of a solution’s pH value and pOH value is equal to 14. If we want to calculate the pH but only have the concentration of hydroxide ions, we can calculate the pOH value and subtract it from 14.
