**Instructions for Determining the Principal Chemical Form(s) and pH Characteristics:**When the following compounds are dissolved in 1 L of water, identify the structure of the principal chemical form(s) that determine the pH. Additionally, specify whether the pH of the solution is governed by weak acid, weak base, ampholyte, or buffer chemistry. Please note that you should not perform pH calculations.**a. 0.1 mole H₂NCH(CH₃)CO₂H** - **pKₐ (CO₂H)** = 2.34 - **pKₐ (NH₂)** = 9.87**b. 0.05 mole HNO₃ and 0.1 mole H₂NCH₂CH₂NH₂** - **pKₐ₁** = 6.85 - **pKₐ₂** = 9.93**c. 0.1 mole HSCH₂CH₂CO₂H** - **pKₐ (CO₂H)** = 4.34 - **pKₐ (SH)** = 10.27For each case, evaluate the ionizable groups based on the given pKₐ values to determine the predominant species in solution. Consider the nature of the solute (acidic, basic, amphoteric) to classify the chemistry that defines the solution's pH.

Acid are proton donors whereas bases are proton acceptors. Weak acids do not dissociate completely…

1. 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 pH 5. How much HCl, in equivalents/L, must be added to this sample to make it pH 5 if the total carbonate concentration is 102 M and the initial pH is 10? Note that the total carbonate is the sum of all of the carbonate species ([H2CO3]+[HCO3] + [CO2]) present in the sample. What are the acid-base pairs responsible for buffering in this sample?
