(10) 6. A student was given a white solid for an unknown. Its melting point range was 78-81 °C. The student has previously worked with naphthalene and observed that it was a white crystalline solid with a melting point of 80.3 °C. (a) Can the student conclude that the unknown is naphthalene based on this information? Why or why not? (b) What additional experimental work should be done to verify this compound?

Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry.
