The simulation will run on most laptops, desktops and touch-enabled devices such as tablets, iPads or phones. (Note: Touch enabled support is still under development, and may be a bit 'clunky').
Please use the HELP tab for information on how to pour one solution to another.
1.) Use the virtual lab to answer the questions below.
a. The solution labeled "1.00g NaCl" contains 1.00g of NaCl dissolved in water. Use the solution viewer to determine the number of grams of Na+ and Cl- in the solution, and confirm that these add to 1.00g.
b. The solution labeled "1.00g AgNO3" contains 1.00g of solid AgNO3. Add 100ml of water to this solution. Use the solution viewer to determine the number of grams of Ag+ and NO3- in the solution.
c. Now add the 1.00g of solid AgNO3 to the 1.00g solution of NaCl. Write down the mass of each species in solution and the mass of solid AgCl formed. Confirm that the amounts of these species are consistent with what you say in parts (2) and (3).

2.) The solution labeled "Solution 1" in the virtual lab stockroom contains 2.00 grams of Sodium Chloride.
a. How many grams of Silver Nitrate must be added to the solution to completely react with Sodium Chloride according to the reaction above? Show your calculations. _____ (1 mark)
b. Use the virtual lab to add that amount of Silver Nitrate to the solution. Check to make sure the reaction was complete, by making sure the amount of Ag+ and Cl- in the solution are both less than 0.01g.
3.) The solution labeled "Solution 2" in the virtual lab stockroom contains 3.00 grams of AgNO3.
If excess NaCl is added to the solution, how many grams of AgCl(s) will be formed? Show your calculations. _____
4.) Use the virtual lab to check your answer to 3 (a). Explain the laboratory procedure you used to perform this check.
To complete the given task, you need to access the virtual lab titled "Textbook Style Limiting Reagents Problems" on Chem collective. Here are the steps to follow:
1. Open a web browser on your Windows or Macintosh computer and ensure you are using Firefox or Chrome.
2. Navigate to the Chem collective website and look for the "Virtual Lab" section.
3. Locate the "Textbook Style Limiting Reagents Problems" virtual lab and click on it to access the simulation.
4. Note that the simulation should work on most laptops, desktops, and touch-enabled devices such as tablets, iPads, or phones. However, touch-enabled support might still be under development and may not be as smooth as using a mouse or trackpad.
5. If you need assistance on how to pour one solution into another, click on the "HELP" tab within the virtual lab. There you will find instructions on how to perform this action.
Now, let's move on to the questions:
1a. In the virtual lab, locate the solution labeled "1.00g NaCl." Use the solution viewer tool provided to determine the number of grams of Na+ and Cl- ions in the solution. Confirm that their sum adds up to 1.00g.
1b. Find the solution labeled "1.00g AgNO3" and add 100ml of water to it. Use the solution viewer to determine the number of grams of Ag+ and NO3- ions in the resulting solution.
1c. Add the 1.00g of solid AgNO3 to the 1.00g solution of NaCl. Note the masses of each species in the resulting solution and the mass of solid AgCl formed. Confirm that these amounts are consistent with what you observed in parts 1a and 1b.
In Table 1, record the masses of each species after the reaction.
Now let's proceed to question 2:
2a. The solution labeled "Solution 1" in the virtual lab stockroom contains 2.00 grams of Sodium Chloride (NaCl). You need to calculate the amount of Silver Nitrate (AgNO3) required to completely react with Sodium Chloride according to the given reaction. Show your calculations and write down the answer.
2b. Add the calculated amount of Silver Nitrate to Solution 1 using the virtual lab. Check if the reaction is complete by ensuring that the mass of Ag+ and Cl- ions in the solution is both less than 0.01g.
Moving on to question 3:
3. The solution labeled "Solution 2" in the virtual lab stockroom contains 3.00 grams of AgNO3. Calculate the amount of AgCl(s) that will be formed when excess NaCl is added to the solution. Show your calculations and write down the result.
Finally, in question 4:
4. Use the virtual lab to check your answer to question 3a. Explain the laboratory procedure you used to perform this check.
By following these instructions, you should be able to complete the given task using the "Textbook Style Limiting Reagents Problems" virtual lab on Chem collective.
