BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the

A Tale of Two Thomases The tale of the first Thomas in this chapter is about the Thomas from the Bible. This Thomas had a great importance. He was involved in three big events in the Bible. The first being when he went with Jesus to see Lazarus. The second is at the Lord’s Supper‚ where Thomas didn’t fully understand how everyone was supposed to get to heaven after Jesus died. He was unsure of how to get there if Jesus didn’t tell where he was going. Later‚ Jesus explains that He is the Way

obstacles to a ‘two-state solution’ to the Israel-Palestine conflict? On December 1st 2003‚ a group of Palestinian and Israeli experts presented a plan which could serve as a blueprint for a ‘two-state solution’ to the Israel-Palestine conflict. (Golan‚ 2008) It was presented in Geneva and is therefore often referred to as the ‘Geneva accord’. It states that the conflict and all claims would have to end and that Israel and Palestine have to mutually recognize their right to two separate states

11 Service Department and Joint Cost Allocation Solutions to Review Questions 1. Companies allocate costs to estimate or assess the costs of their activities (products‚ processes‚ etc.). It is an estimate and subject to the problem that cost allocation contains an arbitrary element. Not allocating costs‚ however‚ is also an estimate—an estimate of zero. This may be appropriate for some decisions‚ but not for others. Some of the disadvantages (costs) include: (1) Additional

1. Solution is a homogeneous mixture composed of only one phase. In such a mixture‚ a solute is a substance dissolved in another substance‚ known as a solvent. Suspension is a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye and eventually‚ they settle out of the mixture. A colloid is a substance microscopically dispersed throughout another substance. Unlike colloids‚ suspensions will eventually settle. The suspended particles are visible

Discuss whether taxation is the most effective solution to market failures arising from negative externalities Market failure is when the free market fails to provide an efficient allocation of resources. Negative externalities are the costs to a third party of a particular action‚ and it is where the social cost is greater than the private cost. Taxation is a solution to correct market failure which is arising from negative externalities. Introducing an indirect tax‚ (a tax levied on goods and

identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three

TUTORIAL1 WITH INFORMATION TO SOLUTIONS 1. For most products‚ higher prices result in a decreased demand‚ whereas lower prices result in an increased demand. Let d = annual demand for a product in units p = price per unit Assume that firm accepts the following price-demand relationship as being realistic: d = 800 – 10p where p must be between $ 20 and $70. a. How many units can the firm sell at the $ 20 per-unit price? At the $ 70 per-unit price?
