STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have a "standard"

Five bases of power Social psychologists John R. P. French and Bertram Raven‚ in a now-classic study (1959)‚ developed a schema of sources of power by which to analyse how power plays work (or fail to work) in a specific relationship. According to French and Raven‚ power must be distinguished from influence in the following way: power is that state of affairs which holds in a given relationship‚ A-B‚ such that a given influence attempt by A over B makes A’s desired change in B more likely.

Based on this definition‚ it is expected that the number of megacities in the world will be mostly located in the developing world. However‚ the definition of megacities based on the population size is arbitrary given that the population in any given city changes with context and time. In the ancient times‚ for example‚ Rome‚ which has a population
