BUFFER SOLUTION Buffer solution is a solution which resist any change in its pH an addition of strong acid or alkali. Types 1 Mixture of weak acids with their salt with strong base i.e. (weak acid + salt of weak acid , conjugated base) 2 Mixture of weak bases with their salt with strong acid i.e. (weak base + salt of weak acid , conjugated acid) Examples: H2CO3/NaHCO3(Bicarbonate buffer) (Carbonic acid and Sodium Carbonate) CH3COOH/CH3COONa(Acetate buffer) (Acitic acid and Sodium acetate)

MGMT530 – Conference Decision Week 1 Case Analysis Template 1) Define the decision problem? As indicated by the scenario it seems that the decision problem is a matter if the accounting systems annual conference that is previously scheduled to occur on September 13-16,2005 should be canceled, due to the fact Hurricane Katrina has occurred and demolished building and homes leaving them in ruin in the city of New Orleans, Louisiana. The primary issue thus becomes does the board or committee

water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing the conjugate base anion in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment you will prepare a buffer solution and observe its behavior when mixed both with an acid and a base. You will also compare the behavior with that of solutions containing only the

establish the criteria, consider a solution, select a solution, implement a solution, and follow-up on the solution (Cheesebro et al., 2010). I will hold a meeting with my team so we can define the problem, and we all can come up with a clear understanding of why these billing issues have occurred. Then we will analyze the findings of what the team has found. I will then have my team come up with a list of solutions. We will then start to consider all the solutions that have been provided, select the
