"Hello, could you please help me?
What happens in this inorganic chemistry reaction:
In a test tube, 1 mL of 5% MgSO4 is added, followed by the addition of 10 drops of oxine (C9H7NO).
What is the chemical equation that occurs and what is observed in the test tube at the end?"

Re: chemical equations
Oxine, 8- Hydroxiquinoline is a complex agent and reacts with metals, like Magnesium

Re: chemical equations
The chemical reaction that occurs in the test tube when adding 1 mL of 5% MgSO4 and 10 drops of oxine (C9H7NO) can be the following:
2C9H7NO + MgSO4 -> (C9H6NO)2Mg + H2SO4
In this reaction, oxine (C9H7NO) reacts with magnesium sulfate (MgSO4) to form a coordination complex called magnesium oxinate [(C9H6NO)2Mg] and sulfuric acid (H2SO4) as a byproduct.
Observations:
At the end of the reaction, some changes may be seen in the test tube. These observations may vary depending on the specific characteristics of the reaction and the experimental conditions. Some possible observations may include:
Color Change: There may be a change in the color of the solution in the test tube, either due to the formation of a colored complex or the presence of sulfuric acid.
Precipitate Formation: A precipitate may form in the test tube as a result of the reaction between the reagents. This arose from the specific properties of the compounds involved.
Gas release: If there is a gas release, bubbles or a change in the volume of the solution may be observed in the test tube.
It is important to note that observations may vary depending on the exact concentrations of the reagents, the reaction conditions, and the presence of other compounds in the mixture. To get a more accurate description of the observations, it is necessary to perform the experiment under controlled conditions and measure the changes precisely.

Re: chemical equations
I am of the same opinion that oxine (C9H7NO) reacts with magnesium sulfate (MgSO4) to form a coordination complex called magnesium oxinate

Re: chemical equations
I think it depends on your 10 drops more or less. Is it possible that when the ratio is not enough, there will be no reaction between them?

Re: chemical equations
No, there will be every time a reaction.

Re: chemical equations
No, chemical reactions happen under molecular units, not drops.frittermiaow wrote: ↑Wed Jul 12, 2023 9:03 pm I think it depends on your 10 drops more or less. Is it possible that when the ratio is not enough, there will be no reaction between them?
