A question in analytical chemistry.
I performed an EDTA titration. Based on the Calcium carbonate, the EDTA concentration was 5.294*10^-3 mol/L
find the concentration of Ca2+ and Mg2+ in a sample.
The sample titrated was 5 mL, the whole sample 100 mL (microwaved digested) and the mean EDTA volume used was 4.88mL.
Can you please show me how to calculate.
a buffer is created by mixing 26 mL of 3.3M sodium formate and 16 mL of 3 M formic acid. What is the capacity of the buffer if 0.2 M NaOH is added?
