The PH range of the effective buffer of NAHC2O4 is 3.5-5.2
How to compute PH level?
- pH is the negative base 10 logarithms ("log" on a calculator) of the hydrogen ion concentration of a solution.
- To calculate it, take the log of a given hydrogen ion concentration and reverse the sign.
What is the pH range of a buffer solution?
- Buffers are generally good over the range pH = pKa ± 1.
- The ammonia buffer would be effective between pH = 8.24 - 10.24.
- The acetate buffer would be effective in the pH range from about 3.74 to 5.74.
- Outside of these ranges, the solution can no longer resist changes in pH by added strong acids or bases.
