ballads for example “Clancy of the Overflow”‚ Henry Lawson provides a more balanced view of the bush in his poems‚ in particular “Up the Country.” Poem – Clancy of the overflow by Banjo Paterson Topic sentence – “Clancy of the Overflow” is typical of an Australian Bush Ballad. In this poem‚ Clancy serves as the representation of what Australians should be like‚ which is wild‚ adventurous‚ pioneering‚ friendly and free. Body - Paterson’s poem “Clancy of the overflow” criticises the dynamics of town

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)

Experiment 1 : Design and preparation of buffers effective at different pHs Abstract The body uses natural buffers to maintain the many different pH environments in our body. This is important for optimum activity of our enzymes. When doing experiments in vitro using these enzymes it is important to mimic intracellular conditions using artificial buffer systems in order to obtain accurate results. In this experiment the buffering properties of three artificial buffer systems containing acetic acid‚ Gylcine

Conclusion Both Kool Aid and Gatorade contain buffers. For the buffer in Kool Aid‚ pKa1 ≈ 3.70‚ pKa2 ≈ 4.90‚ pKa3 ≈ 6.50 and for the buffer in Gatorade‚ pKa1 ≈ 4.50‚ pKa2 ≈ 5.40‚ pKa3 ≈ 6.70. Discussion of Theory A buffer capacity is the maximum amount of hyrdrogen or hydroxide ion that can be added to a buffered solution before a significant change in the pH occurs. Increasing the concentration of the buffer can increase the buffer capacity of a solution. At the half equivalence point‚ the moles

t Design and preparation of buffers effective at different pHs Abstract These experiments aimed to determine the optimum pH ranges various buffers are effective and provide opportunity for the use of the Henderson-Hasselbalch equation to prepare a buffer of a specific pH. Three different buffer systems were initially investigated; volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent

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:
