IUPUI October 12‚ 2012 Titration of Acids and Bases Introduction According to Arrhenius definition‚ acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base‚ a method called acid-base titration is used. The end of

1. Prepare the burette and fill with the sodium hydroxide solution to 50ml. 2. Pipette the KH(C8H4O4) solution into a conical flask. Use three drops of phenolphthalein as the indicator. 3. Titrate carefully until a colour change from colourless to pink is observed. 4. Perform a rough titration first‚ then repeat until 3 concordant

Redox Titration Analysis of a Commercial Bleach A. Purpose ! ! ! To review oxidation-reduction reactions and their stoichiometry. To learn the concept and technique of redox titration. To determine the percent (m/v) of an active ingredient‚ sodium hypochlorite (NaOCl)‚ in a commercial bleaching agent. B. Theoretical Background Whereas acid-base reactions involve the transfer of a proton‚ oxidation-reduction or redox reactions involve the transfer of electrons from one substance to

Introduction Titration is a volumetric analysis technique used to find the concentration of an unknown substance. There are several types of titration but the one used for this experiment is called acid-base titration as the substance we are titrating is acidic. Acid-base titrations are based on the neutralisation reaction between the analyte and the acidic or basic titrant. The analyte is the solution of unknown concentration and the titrant is the solution of accurately known concentration used

final project entails systematic extraction of decision-aiding insights out of a dataset. The project will provide hands-on experience in conducting and interpreting different types of function-wise statistical analysis. The focus of the analysis will be on marketing strategies and analysis-related topics (South University Online‚ 2012). The sample set was examined thoroughly to reveal findings relevant to the marketing strategies and the interpretation of the data. The median income is between

1.7.2 Coal Bottom Ash in Self-Compacting Concrete Coal Bottom Ash has gained a great consideration as an alternative for replacing fine aggregates. Coal Bottom Ash has physical characteristics are same as that of naturally found sand which makes it suitable for replacing sand in concrete. Coal Bottom Ash represents good pozzolanic element reactivity when it comes in contact with finer elements. Many researchers in their research work claimed that the properties of Self-Compacting Concrete comprised
