Addendum 3: How to prepare the electrode storage solution
1. Dissolve 22.365 grams of potassium chloride reagent (KCL) in the 100mL distilled water.
2. Pour the 50mL of KCL solution into the beaker.
3. Pour the 50mL of pH4.01 standard buffer solution into the same beaker.
4. Stir the solution until the solution has thoroughly mixed. Preparation is completed.
Addendum 4: How to prepare the conductivity standard solutions
Place AR potassium chloride reagent in a 50mL beaker and dry in an oven for 3 to 5 hours at 105°C, then cool to room temperature in desiccator.
