6.7.8.For a particular application in my lab, we often need to make a formic acid buffer. The chemical formula for formic acid is HCO₂H.To make this buffer, let's say we start with 2.53 M sodium formate in 1 L of water (and assume 1L of volume throughout this problem).5.2.3. (4.1.Using the chemical formula information above, show the chemical reaction of formate with water to form products (hint: whatpart of the sodium formate reacts with the water?) Make sure you include the phases of matter.What is the value of the equilibrium constant for this reaction?What is the pH of the solution right now?Let's say we add HCl, show the reaction that would occur (what part of the HCI reacts with what part of the equilibrium reactionoutlined in part 1?)Let's say we add 0.45 moles of HCI. What is the resulting pH now?Ok, to the solution in #5 above, after we add the HCI, we now add 0.23 mol NaOH. Identify the component in the solution withwhich the NaOH will react.What is the new pH of the solution described in #6?At which stage in here (Identify a number 1, 4, or 6) does this solution become a buffer and briefly describe why.

As per Bartley expert guidelines, I am allowed to answer first one question at a time. Please re…

1. How do you prepare a 100mL of 0.1 M phosphate buffer?To make 100 mL of 0.1 M phosphate buffer: Calculate the amount of sodium phosphate needed. moles of sodium phosphate = (0.1 mol/L) x (0.1 L) = 0.01 moles mass of sodium phosphate = moles x molar mass = 0.01 moles x 142 g/mol = 1.42 g Dissolve 1.42 g of sodium phosphate in distilled water in a 100 mL volumetric flask. Adjust the pH of the solution to the desired value (usually around 7.4) using a strong acid or strong base. Bring the solution to the final volume (100 mL) with distilled water. 2.
