Determination of the concentration of ethanoic acid in commercial vinegar Introduction: The aim of the experiment was to determine the molarity of ethanoic acid in table vinegar by titrating a sample with alkali sodium hydroxide (NaOH) with a known concentration of 0.1molL-1. The equation of the reaction between ethanoic acid and sodium hydroxide is as follows: CH3COOH + NaOH CH3COONa + H2O When the titrations end point is determined and volumes of reactants are measured the concentration

important to evaluate how the activity went. This is because it gives both the children and staff members a chance to reflect on the learning which has taken place and establish whether or not the learning objective was achieved. To evaluate effectively you should refer to the original learning objective to see what you set out to achieve and then reflect on the outcome and whether or not this outcome was satisfactory and that the targets you set have been met.

Outline and evaluate the ‘WMM’ (12marks) The working memory model (WMM) has four components. The central executive controls and monitors the operation of the other 3 components. It also allocates attention. The phonological loop is sub-divided into 2 smaller components‚ the articulatory control system‚ where information is rehearsed sub vocally or in the inner voice and the phonological store where speech is held for a very brief duration in the inner ear. The third component is the visuo spatial

Explain how the SRRS was devised and evaluate the use of this technique. (8marks) Holmes and Rahe (1967) developed the Social Readjustment Rating Scale (SRRS) which identifies 43 stressful life changes that can contribute to stress-related illness. Each one of the 43 stressful life events was awarded a Life Change Unit depending on how traumatic it was felt to be by a large sample of 400 participants. The highest Life Change Unit is 100‚ being death of a spouse. Participants calculate a total value
