Is freshly squeezed grapefruit juice a heterogeneous mixture?
Yes, freshly squeezed grapefruit juice is considered a heterogeneous mixture. This is because it contains different components, such as pulp, juice, and possibly seeds, that do not fully blend together and can be visually distinguished. Over time, the solids may settle, further demonstrating its heterogeneous nature.
Why is it important that fehlings solution be freshly prepared?
Fehling's solution contains copper sulfate and potassium tartrate which can oxidize and degrade over time, leading to inaccurate results. Freshly prepared Fehling's solution ensures the reagents are at their optimal concentrations for reliable testing of reducing sugars.
What happens when a freshly precipitated Fe (OH)3 is shaken with a little amount of dilute solution of FeCl3?
When freshly precipitated Fe(OH)3 is shaken with a dilute solution of FeCl3, the hydroxide can dissolve back into the solution due to the formation of soluble complexes. This occurs because FeCl3 can provide additional iron ions (Fe³⁺), which can interact with the hydroxide ions (OH⁻) from Fe(OH)3, leading to the dissolution of the precipitate and the formation of soluble iron species. The process can also lead to the formation of a colloidal suspension if the conditions favor it.
What kind of mixture is freshly-brewed black coffee?
Freshly-brewed black coffee is a homogeneous mixture. It consists of water as the solvent and coffee particles as the solute, which dissolve to form a uniform solution.
Why is it important that the Fehling's solution for use as a reagent by freshly mixed?
Fehling's solution contains copper sulfate and alkaline tartrate, which can deteriorate upon prolonged exposure to air. Freshly mixed Fehling's solution ensures the copper ions are in their active state for proper oxidation reactions in detecting reducing sugars, providing accurate results. Deterioration of the solution over time can lead to false negative test results.
Is freshly squeezed grapefruit juice a solution and why?
No because it has to be stirred to look like one substance. It is a suspension.
