ion undergoes reduction to Mn2+ this is the equation: 8H+(aq) + Mno4-(aq) + 5e- Mn2+(aq) + 4H2O Since the KMnO4 – ion is violet and the Mn2+ ion is nearly colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing). The titration which involves the oxidation of Fe2+ ion to Fe3+ by permanganate ion‚ is carried out in sulfuric acid to prevent air-oxidation of Fe2+ (we can them determine

Cost reduction Generally defined as the act of cutting costs to improve profitability. Cost reduction‚ should therefore‚ not be confused with cost saving and cost control. Cost saving could be a temporary affair and may be at the cost of quality. Cost reduction implies the retention of essential characteristics and quality of the product and thus it must be confined to permanent and genuine savings in the costs of manufacture‚ administration‚ distribution and selling‚ brought about by elimination

9.1.1 Define oxidation and reduction in terms of electron loss and gain. Oxidation: the loss of electrons Reduction: the gain of electrons 9.1.2 Deduce the oxidation number of an element in a compound. Always determine elements that never change their oxidation number then ensure the charge of whole molecule is right. N.B. Atoms in elemental state have oxidation numbers of 0 9.1.3 State the names of compounds using oxidation numbers. Example of this in iron‚ can be iron(II) or iron(III) 9.1.4 Deduce

Cognitive Functioning in Older Adults PSY317: Cognitive Functioning in the Elderly Ragota Berger June 25th‚ 2012 Cognitive Functioning In Older Adults Not only is the country’s population growing‚ it is aging as well. Older adults are the fastest growing population on the charts right now. There is no point and time when a person overnight just becomes “old.” Obviously everyone knows we simply just age; it comes with getting older. This thing called “aging” happens to everyone at a different

Interacting with Older Adults The future of health care in America will critically focus on older adults and chronic diseases. Presently‚ the Center for Disease Control and Prevention [CDC] (2013) reported that more than half of older adults have multiple chronic conditions. Accordingly‚ major health agencies urge care providers to expand their education and training in gerontology. Similarly‚ to meet the needs of the seniors effectively‚ medical staff need to be well-informed of the culture

The purpose of this lab was to measure the reduction potentials of metals and to understand how a reduction-oxidation relationship works to produce spontaneity. Lastly‚ these results were used to determine the Faraday’s constant and Avogadro’s number by electrolysis‚ which is chemical decomposition produced by passing an electrical current through a solution with ions. The primary objective of part one of this experiment was to discover how the properties of an electrochemical cell works. An electrochemical

discrimination faced by older adults lies in the LGBT community. As estimated by‚ (Fredriksen-Goldsen‚ Kim‚ Shiu‚ Goldsen & Emlet‚ 2015) “2.4% of adults aged 50 and older identify as lesbian‚ gay‚ bisexual‚ or transgender.” This accounts for more than 2.4 million older adults‚ in the United States. In comparison to heterosexuals of the same age‚ lesbian‚ gay male and bisexual older adults are more likely to experience mental distress. Due to their life course and different historical events‚ older adults grew
