One way is too to collect just solute sugar, heat over very low heat to evaporate as much water as possible to give yourself a saturated solution. Then crystallize sugar and filter in the lab you'd wash with a suitable solvent and dry under vacuum To collect just the solvent water distill over moderate heat to collect water.
Answer:
K = 4.07x10⁻³
Explanation:
Based on the reaction:
NH₄I(s) ⇄ NH₃(g) + HI(g)
You can define K of equilibrium as the ratio of concentrations of reactants and products, thus:
K = [NH₃] [HI] / [NH₄I]
But, as NH₄I is a solid, is not taken into account in the equilibrium, that means K expression is:
K = [NH₃] [HI]
As the concentrations in equilibrium of the gases is:
[NH₃] = 4.34x10⁻²M
[HI] = 9.39x10⁻²M
Equilibrium constant, K, is:
K = 4.34x10⁻²M * 9.39x10⁻²M
<h3>K = 4.07x10⁻³</h3>
The answer to this would be a physical change. Physical changes are changes that affect the form of a chemical substance, but not the chemical composition itself. Hope this helped!
Answer:
In a solution the solvent is the liquid that the solute is added to.
Explanation:
Solute + Solvent = Solution.
For example: An aqueous solution of 10 g of NaCl in 100 g of water
NaCl → solute → what you dissolved
H₂O → solvent → where you dissolve
