Concentration vs Solution Volume 4. Given this graph, what can you say about the experiment? conc (M) 0.18 0.6 0.28 0.38 0.48 0.58 solution volume (L) A. Amount of solute was the independent variable B. Amount of solution was the independent variable C. Concentration was the independent variable D. More than one of these 4. Answer and explanation with support
Answers
Answer is option B. : Amount of solution is independent variable.
Explanation
The main factors taht affect concentation of a solution are,
1.amount of solute
2.amount of solvent
3.temperature
4.solubility of the solute
5.nature of solute and solvent etc.
From these we can easily conclude option C is incorrect.because concentarion is a depend on number of factors.
Here in the graph ,gives the relationship between concentration(molarity) and volume of solution.volume of solution increases means that, volume of sovent added again or any other factor that affect volume change.
The solution is the combination of the solute and the solvent.
From the equation we can understand that concentarion depends on amount of solute (threfore option A is incorrect )
option B : From the equation ,it is very clear that molarity depends on volume of solution .but volume of solution means approximately equal to volume of solvent.
Volume of solvent inreases, volume of solution increases then concntration decreases.that is shwon in graph.
.
moles of solute Molarity(M) = Liters of solution
