A student had prepared three ethyl-substituted benzaldehydes, but neglected to label them. The student at the next bench said they could be identified by brominating a sample of each and determining how many bromo-substituted products were formed. Is the students advice sound?
Slide 39 Aqueous Solutions and Chemical Analysis Quantitative Analysis when to find how much of a substance is present. Useful when finding concentration of a substance in a solution. Quantitative Analysis Gravimetric Analysis: Titration: Calculation of a Use the mass as a base solute’s concentration in a as knowledge solution. Finding gravimetric mass: - Example: A 0.8633 g sample of an ionic compound containing Cl ions and an unknown metal cation is dissolved in water and treated with an excess of AgNO . If 1.5615 g of AgCl solid forms, what is mass % of Cl in the original 3 compound
