In this report I will explain how and why laboratory and industrial scale differ using the example of preparation of aspirin. The first difference is that instead of weighing the 2-hydroxybenzoic acid on scales on a work bench in a beaker as you would in small scale‚ it is easier and safer to weigh it onto scales‚ in a plastic bag on the floor.

and many comedies. One comedy he wrote was the play Measure for Measure. It can be argued that because of the deep gloom and moral concerns underlying this play‚ Measure for Measure can be considered a problem play. Many questions are raised in the play about justice and mortality and these questions also lead the reader to think why the play was named Measure for Measure and not something else. There are many ways the title Measure for Measure‚ by William Shakespeare‚ can be interpreted such as:

HOW DOES SHAKESPEARE INFUSE ACT ONE OF ‘MEASURE FOR MEASURE’ WITH CONTEXTUAL REFERENCES? ‘Measure for Measure’ is set in Vienna‚ in 1603. It was written just after James the first‚ a protestant ruler came to the throne in England after the death of Queen Elizabeth‚ who was catholic. Religion is a big part of the play‚ especially in Act one‚ when the new proclamation is first introduced. Both Catholics and Puritans believe that sex before marriage is wrong‚ and during James the 1sts reign‚ the

During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH

Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH‚ which stands for the proportion of hydrogen ions in a solution‚ could be acidic (acidosis)‚ neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral; meaning the amount of hydrogen

Procedure: Part I: Titration with an Indicator 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Add two drops of the indicator‚ phenolphthalein‚ to the acid in the flask. 7. Using the slider on the right hand side‚ add NaOH to the HCl in the Erlenmeyer flask (This action

differences between the Stanford Binet Intelligence Scale and the Wechsler Intelligence Scale. Intelligence: According to the Oxford Dictionary in psychology terms intelligence is the general mental ability involved in calculating‚ reasoning‚ perceiving relationships and analogies. It is also the ability to learning quickly‚ storing and retrieving information‚ using language fluently and adjusting to new situations. Stanford -Binet Intelligence Scale In 1857-1911 Alfred Binet invented the method

Q.2 . What is groupthink. Explain. [10] According to Irving Janis(1972) ‚ groupthink is "a deterioration of mental efficiency‚ reality testing‚ and moral judgment resulting from in-group pressures". Thus‚ the overemphasis on consensus and agreement leads members to be unwilling to evaluate group members’ ideas critically. This hinders decision-making and becomes an obstacle to group productivity. Certain conditions favour the development of groupthink. i) The first condition is high cohesiveness

undertaken by the International Labour Organisation (ILO) and is a more direct assessment of unemployment‚ rather than those who claim benefit. It is based on an interview of a sample of 60‚000 households (approximately 120‚000 people) and tries to measure ‘unemployment’ as a whole‚ rather than those simply claiming benefits. To be considered as being unemployed individuals must: Have been out of work for 4 weeks. Be able to start work in the next 2 weeks‚ so they must be readily available

As businesses grow and their outputs increases‚they commonly benefit from a reduction in average costs of production.Total costs will increase with the increase in output‚but the cost of producing each unit falls as output increases .The reduction
