What are the units for measuring the concentration of the solutions in the simulator?
The concentration of a solution can be measured in mass per given volume of solution, eg grams per dm³ (g/dm³). Students should be able to: calculate the mass of solute in a given volume of solution of known concentration in terms of mass per given volume of solution.
What is chemistry simulation?
The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab.
How does the concentration change as additional water is added?
Dilutions. When additional water is added to an aqueous solution, the concentration of that solution decreases. This is because the number of moles of the solute does not change, but the total volume of the solution increases.
How might you get that concentrated solution to become saturated?
b. How might you get that concentrated solution to become saturated? Possible Answer: You can evaporate the solution until there is solute at the bottom of the tank. Then add enough additional solution for it to become saturated.
What is an interactive simulation?
1. A dynamic case study of a particular social or physical reality, in which the participants take on roles with well-defined responsibilities and constraints in order to reach a goal (Gredler, 2001). Learn more in: Experiential Learning in the Myself Project.
What happens as a solution is heated?
(i) If a saturated solution is heated to a higher temperature, it becomes unsaturated. Hence, the saturation point of a solution increases with the increase in temperature as there is an increase in solubility of the solute.
Which factor is more important in concentration of solution?
Answer and Explanation: Volume of the solution in liter.
How does a solution become supersaturated Quizizz?
How does a solution become supersaturated? dissolve lots of solute in it.
What is the formula of solution?
The standard formula is C = m / V, where C is the concentration, m is the mass of the solute, and V is the total volume of the solution.
How do you calculate standard solution?
You will need to calculate:
- M, the molar mass of the compound used as the primary standard M(compound) = sum of the molar mass of each element multiplied by the number of atoms present in the formula.
- n, the amount in moles of the compound you used as the primary standard n = m ÷ M.
How do you calculate mixing solutions?
Calculate appropriate v/v dilution using the formula C1V1 = C2V2 where C represents the concentration of the solute, and V represents volume in milliliters or ml. An example would be combining 95 percent ethanol with water to mix 100 ml of 70 percent ethanol. The calculation is 95% X V1 = 70% X 100ml.
What are the benefit of visual interactive simulation?
In business, the use of visual interactive simulation (VIS) can lead to significant benefits: improved efficiency, reduced costs and increased profitability. However, these benefits are rarely attained since only a few managers are aware of the technology.
How do you create a virtual laboratory?
1) Firstly, go to the Web Console, login and click on Virtual Labs. 2) Click on ‘Create Virtual Lab’ in the top-right corner of the page and select the name of a Virtual Lab Policy from the Virtual Lab Template list, then click Next. One will not see this box if they just have one VM lab template available.
