Answer:
Increased the concentration
Explanation:
Complete Question
Open the simulation by pushing the play button. Begin by dragging the concentration tester overto the liquid and add drink mix until the concentration reaches approximately 2.oo mol/L. This means there are 2.00 moles of the drink mix in 1 Liter of the solution. Add more drink mix until you notice a color change. Have you increased or decreased the concentration? (Higher number means a higher concentration).
Solution
Drink mix is basically the solute which is added to solvent i.e water.
The higher is the amount of drink mix in the solvent, the higher is the concentration of the solute and hence darker is the color of the drink.
Hence, in the case the concentration of the drink has been increased.
