Using the "My solution" section of the applet tinyurl.com/valacidsim, answer the following questions:

Acids

• What are the light grey molecules?

• What are the red ions?

• How does the initial concentration of acid in the solution (more mol/L, or particles per litre) affect the pH of your solution?

• How does the strength of your acid affect the amount of grey molecules?

• How does the strength of your acid affect the pH of your solution?

• How does the strength of your acid affect the conductivity of your solution?

Bases

• What are the blue ions?

• How does the initial concentration of base in the solution (more mol/L, or particles per litre) affect the pH of your solution?

• How does the strength of your base affect the amount of grey molecules?

• How does the strength of your base affect the pH of your solution?

• How does the strength of your base affect the conductivity of your solution?
