Common Ion Effect HA(aq) + H2O(l) ⇔ A−(aq) + H3O+(aq) • Adding a salt containing the anion NaA‚ which • is the conjugate base of the acid (the common ion)‚ shifts the position of equilibrium to the left This causes the pH to be higher than the pH of the acid solution 9lowering the H3O+ ion concentration

Describe and Evaluate the Multi-Store Model of Memory The multi-store model of memory (MSM) is an explanation of the process of memory. Richard Atkinson and Richard Shiffrin first illustrated the multi-store model‚ in 1968‚ it explains how we hear‚ see and feel many things but only a small number are remembered and other aren’t. There is strong evidence of three different stores suggesting that the basis of the MSM is reliable. However there has been some criticism of the MSM‚ most importantly

GENERAL APPROACHES FOR DOSE ADJUSTMENT IN RENAL DISEASE Renal insufficiency can markedly alter one or more of the pharmacokinetic parameters of a drug including oral bioavailability‚ volume of distribution‚ drug binding to plasma proteins‚ and most importantly the rates of metabolism and excretion‚ i.e.‚ drug clearance.. To minimize drug toxicity and maximize therapeutic benefits‚ it is often necessary to adjust drug dosage in proportion to the degree of renal insufficiency. A drug will most

Outline and evaluate the working memory model (12) The working memory model (WMM) suggests that there are three main components to human memory. The central executive is the key component of working memory and is what directs attention to particular tasks‚ deciding which ‘resources’ (being the phonological loop and visual-spatial sketchpad) are allocated to which tasks. The central executive has a very limited capacity however‚ and can’t attend to too many things at once. The phonological loop

The textile industry in Bangladesh employs three million people and makes up 80% of the country’s exports (ABC News 2013). However‚ there is a history of unsafe working conditions and deaths (Ahmed and Peerlings 2009; Ahmed 2004‚ 38). A factory collapse recently killed over 1000 workers and as a result‚ various companies are signing a safety accord (Ferguson and Jolley 2013). This is an ethical decision that can impact those company’s stakeholders. The decision can be made under various ethical models

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are
