1. The composition of a buffer relies upon both a weak acid and its conjugate base being present in a solution at an appropriate ratio and amount to resist pH changes. While you make a buffer in lab by adding solids of each into solution, this is impractical, actually, as who has both an acid and conjugate base laying around?! Thankfully, there is another way to make a buffer! Propose a way you can make a buffer if you only have either the acid or conjugate base (considering other, common reagents available in the lab)? Now lot us talk about titrations In one oxnoriment vOu have O 1000 M HOLL

Calculate the buffer capacity of each of your three buffer solutions. It is generally expressed in millimoles of strong acid or base. You may assume linear behavior for the change in pH verses the amount of acid or base added. CHALLENGE QUESITONS FOR YOUR LAB NOTEBOOK 1.

Now, let us talk about titrations. In one experiment, you have 0.1000 M HCI being dispensed from your buret into an Erlenmeyer flask that contains an unknown concentration of a weak base (NaA (e.g., sodium A)). Write out the reaction of HCI with NaA during the course of the titration. b. What is the predominant species at the start of the titration, at the equivalence point, and half way to the equivalence point? You can use theoretical values to help a. you rationalize! 95 of 1680 words English (United States) O Focus MacBook Pro
