All chemistry knowing individuals can recall from their early chemistry knowledge that Acidic materials dissolve in water to produce a net surplus of hydrogen, H+ ions and basic materials dissolve in water to produce hydroxyl, OH- ions and both these behave as electrically charged species in water. It is the concentration of these ions which determines the strength of an acid or a base. Strong acids produce higher concentrations of H+ than weak acids and vice-versa for bases too. We can generalize and say that: most common acids have a high solubility in water i.e. we can put them in water, dissolve them and generate ions in solution; they are not flammable, although some highly concentrated acids may ignite other materials; acids react with metals, sometimes slowly, to produce flammable and explosive hydrogen gas; acids neutralize bases, in other words, hydroge Scholarships for High School Juniors n ions react with hydroxyl ions to produce water and resultant heat. For example, Caustic Soda (a base with chemical formula NaOH) will neutralize a spill of hydrochloric acid (HCl) and the overall reaction will would produce considerable heat and fumes. The presence of water is critical to the acid/base concept. One might consider adding water to acids and bases in order to dilute them and hence make them less concentrated and less hazardous. One rule of thumb in the chemical laboratory is ?A ?W and not W? A? that is acid is always added to water and never water to acid. Addition of water to concentrated acid, the only way to combine the two in a spill situation, can cause splashing and bubbling of acid. Dilution may also cause the solution to heat up due to heat of dilution which, in turn will reduce the solubility of the acid in water and generate acid fumes.
Competitive Pay Policy
Companies competing in different industries among each other do not only oppose one another while trying to sell their good or services, but also they compete for skilled and experienced employees. How a company chooses to attract future employees and keep people working for them is determined by the competitive pay policy. This policy is generally based on three marketing conditions while recruiting new workforce, those conditions are: a) availability of qualified workers in the market, b) the aggressiveness of other employers searching for the same type of workforce; c) company?s abilities in recruiting new people (financial situation, other benefits it can provide). Most of the times in modern business world, company?s competitive pay policies are based on the percentile levels of the targeted market. Generally companies choose market?s 50th percentile or median policy which allows an organization to stay college scholarships for high school seniors competitive and at the same time not spend too much money or benefits for attracting employers. However, some companies do choose to stay above or below this median point in competitive pay system; it may be caused by company?s decision to focus mainly on one of the three earlier mentioned compensation types. Often such companies get exhausted in providing too much of particular sort of payment of benefit, and this results in employees? dissatisfaction. The trick, that every company that wants to be a competitive employer has to learn, is to understand the concept of balance in identifying the best competitive pay policy. The notion of total reward model is the most reasonable one for the employers to consider if they want to attract, retain, and motivate, for further success, employees. This approach is based on the principal of providing an employee with compensations that is money for the provided services.
