### Designing a Buffer System with pH 3.76**Objective:**Design a buffer that has a pH of 3.76 using one of the weak acid/conjugate base systems shown below.#### Buffer Systems:The table shows three potential weak acid/conjugate base systems, their dissociation constants (Kₐ), and their pKₐ values:| Weak Acid | Conjugate Base | Kₐ | pKₐ || --------- | -------------- | --- | --- || HC₂O₄⁻ | C₂O₄²⁻ | 6.4 x 10⁻⁵ | 4.19 || H₂PO₄⁻ | HPO₄²⁻ | 6.2 x 10⁻⁸ | 7.21 || HCO₃⁻ | CO₃²⁻ | 4.8 x 10⁻¹¹ | 10.32 |**Problem:**How many grams of the potassium salt of the weak acid must be combined with how many grams of the potassium salt of its conjugate base, to produce 1.00 L of a buffer that is 1.00 M in the weak base?**Required Calculations:**- grams of potassium salt of the weak acid = ____- grams of potassium salt of the conjugate base = ____### Understanding the Table and ProblemThe table contains valuable information about different buffer systems that can potentially be used to create a buffer solution with the desired pH. Here's a breakdown of the columns:- **Weak Acid:** The chemical formula of the weak acid.- **Conjugate Base:** The chemical formula of the conjugate base that pairs with the weak acid.- **Kₐ (Acid Dissociation Constant):** A numeric value representing the strength of the weak acid in water.- **pKₐ:** The negative logarithm of the Kₐ value, giving a more intuitive measure of acid strength.### Choosing the Appropriate Buffer SystemTo choose the correct buffer system, compare the desired pH (3.76) with the pKₐ values of the acids. The most effective buffer will have a pKₐ close to the desired pH. In this case:- HC₂O₄⁻ has a pKₐ of 4.19, which is close
