Ans. Number 2
NOTE: PRESENT DETAILED SOLUTION 1. A 5.0 gram sample of rock containing CuSO4 was analyzed for its sulfate content. Fifty (50) ml deionized water was added to dissolve the sample. A solution of 0.25 M BaCl₂ solution I was added slowly until all the sulfate were precipitated. The mixture was filtered using ashless filter paper. After ignition in a furnace, cooled and oven-dried, the precipitate obtained weighed 1.2034 grams. Calculate the % Sulfate in the rock sample. 2. Describe the preparation of 500 ml of 0.15M HCI using concentrated hydrochloric acid solution. 3. A solution of sodium hydroxide was prepared by dissolving 40.0 grams of sodium hydroxide pellets to prepare one (1) liter of the solution. During standardization, 35.5 ml of the prepared sodium hydroxide solution was required to titrate 0.500 gram KHP to reached the end point using phenolphthalein indicator. What is the true concentration of the sodium hydroxide solution? What is the % Error? 4. A 5.0 gram sample containing sodium carbonate was dissolved in 50 ml distilled water. Two drops phenolphthalein indicator was added turning the solution dark pink. Then 20 ml of 0.10 M HCI solution was added turning the mixture colorless. Titration required 15 ml of the 0.15 M NaOH standard solution to reached the endpoint which is faint pink Calculate the % analyte in the sample. a. Write the equation of the reaction of the sample and HCI b. Write the reaction equation between the excess acid and NaoH.
