Evaluate the case for and against using a buffer stock scheme to stabilise the price of a commodity such as sugar or tin. A buffer stock scheme is an intervention carried out by the government which aims to limit fluctuations in the price of a commodity. It involves the government and/or local authorities buying these storage stocks and selling them back to the famer. Price stability is indicated by low inflation whereby the value of money is also stable. A buffer stock is an attempt at

PREPARING BUFFERS AND BUFFER CAPACITY INTRODUCTION A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base‚ in relatively equal and "large" quantities. A buffer system can be made by mixing a soluble compound that contains the conjugate base with a solution of the acid such as sodium acetate with acetic acid or ammonia with ammonium chloride. The buffer capacity

CLANCY OF THE OVERFLOW - A.B. "Banjo" Paterson I had written him a letter which I had‚ for want of better Knowledge‚ sent to where I met him down the Lachlan‚ years ago‚ He was shearing when I knew him‚ so I sent the letter to him‚ Just "on spec"‚ addressed as follows: "Clancy‚ of The Overflow". And an answer came directed in a writing unexpected‚ (And I think the same was written in a thumbnail dipped in tar) ’Twas his shearing mate who wrote it‚ and verbatim I will quote it:

Danforth’s decsions in court are formal. He is a person who follows the books and tries to listen to both sides of the argument. However his religious beliefs take over and he begins to show less pity for the accused. This can be seen when Danforth claims Proctor is a witch‚ “What are you? ( Proctor is beyond

Messing 8/3/12 Section 623 Abstract To examine the effectiveness of buffers by titrating two sets of five different solutions using HCl and NaOH and monitoring the pH change of the various solutions. The data collected shows that the buffer systems made with sodium acetate and acetic acid were effect when titrated with the strong acid and the strong base. Comparison of all the solutions shows that the concepts of buffers holds true for the results from the experimentation. Introduction The

1) Natural buffers are chemicals that the body releases into the blood stream to help maintain a healthy pH level. Carbon dioxide (CO2) acts as an acid by donating hydrogen ions when needed and forms carbonic acid when it dissolves in water. Carbonic acid bicarbonate is important for maintaining an acid base balance in the blood as it equalizes the pH (7.5) of the blood. All body fluids have buffers that defend the body against pH changes. A process that affects buffers in the blood is exercise
