Explain the accurate solution of the given question
Question- Environmental Engineering Question.You are taking samples at a contaminated mine site from a carbonate aquifer to determine the concentration of dissolved lead in the sample. To preserve the sample, you acidify it to pH5. How much HCL, in equivalents/L, must be added to this sample to make it pH5 if the total cabonate concentration is 10-2M and the initial pH is 10? Note that the total carbonate concentration is the sum of all the carbonate species [H2CO3]+[HCO3-]+[CO32-] present in the sample.
Part 1- What are the acid-base pairs responsible for buffering in this sample?
I want help to describe the acid-base pairs responsible for buffering.
