Lajos Winkler developed the Winkler Titration Method to determine the amount of DO in water. The endpoint in the Winkler Titration Method is determined by using starch as a visual indicator. 2. In the distillation process, the absence of a reaction when the distillate is mixed with the silver nitrate solution indicates that the distillate is impure water. In a simple distillation set-up, the cooling water exits at the bottom part of the condenser. 3. Water is composed of two atoms of both hydrogen and oxygen. In a water molecule, hydrogen has a partial negative charge. 4. The particles found at the bottom of a sedimentation tank/bottle are called sediments. The purified liquid collected in the distillation process is referred to as the distillate. 5. Sodium hydroxide and sodium chloride are both…

When solid sodium bicarbonate and solid hydrochloric acid were mixed together, no change was observed. When water was added to the solid mixture, bubbles formed. Explain these results.Emmett, a sophomore chemistry major, was trying to separate an unknown mixture. His instructor told him that there was a carboxylic acid, phenol, and amine present in the mixture. He dissolved 3 g of the unknown in 10 ml of t-butyl methyl ether. He then added 10 ml of 3M sodium hydroxide to the mixture. He used a separatory funnel to separate the layers and collected the aqueous layer in an Erlenmeyer flask labeled fraction 1. Then he added 10 ml of 1.5M sodium bicarbonate to the remaining ether. He separated the layers, and collected the aqueous layer in an Erlenmeyer flask labeled fraction 2. Finally he added 10 ml of 1.5 M hydrochloric acid to the ether, and separated the aqueous later in an Erlenmeyer flask labeled fraction 3. Emmett neutralized the respective fractions. He obtained precipitate in fraction 1, and fraction 3. He ran an IR of the solid obtained in fraction 1 and saw a broad absorption at 3500-3300 cm-1 and a sharp absorption at 1710 cm-1. Fraction 3 showed…
