Discuss critically the need for international accounting harmonization and assess the success of the attempts at international harmonization and standardization that have been made up to the present time For decades‚ entities across the world have been using a range of different accounting standards derived from various accounting models. Weber (1992) states that there have historically been four accounting standards models from different areas of the globe: the United Kingdom‚ Continental Europe

Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

of known concentration made from a primary standard. Primary standard solutions are used in determining the concentrations of other solutions to an extremely high accuracy. They are typically used in titrations and other analysis techniques as standardization solutions. A secondary standard solution‚ such as HCl solution‚ is a solution which must be standardized first against a primary standard‚ but afterwards‚ it will be stable enough for titrimetric work (Titration). Titration involves the gradual

Standardization of NaOH and Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration

The molarity of the standards will be found through titration of KHP for NaOH‚ HCl vs the known NaOH‚ and the unknown Soda Ash sample vs the known HCl. II.

The experiment calls for a neutralization reaction‚ the analytes are the acidic soft drink samples and the titrant is the base NaOH. The equation for the titration reaction is as follows: H3C6H5O7 + 3NaOH -----> 3H2O + Na3C6H5O7 But before proceeding to the titration of soft drink samples‚ the exact concentration of NaOH must be known through the process of standardization which involves performing a titration with a known amount of a stable acid‚ which in this case is the monoprotic acid potassium

In the second method‚ the solution is standardized by titrating - a weighed quantity of a primary standard a weighed quantity of a secondary standard or a measured volume of another standard solution. As a result‚ standardization is a process of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured
