Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

Monopoly of starhub: A lump-sum bid would resolve asymmetry of information between EPL and cable TV operators. StarHub won the rights after a bidding war with SingTel and ESPN STARSports (ESS). They realised that it’s a monopoly where consumers are left with no choice‚ simply because StarHub is the only cable TV provider. Them packaging all their services together in a bundle was a very smart move‚ by doing so‚ they could increase their market share. The increase for the sports package was much

BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid and base interactions‚

Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A‚ which determines the strength of the H—A bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Sulfonic acids‚ which are organic oxyacids‚ are a class of strong acids. A common example is toluenesulfonic acid (tosylic acid). Unlike sulfuric acid itself‚ sulfonic acids can be solids. Superacids are acids stronger than 100% sulfuric acid. Examples
