How does the pH of a strong acid or base differ from that of a weak acid or base?

1. Switch to the graph portion of the "views menu" and switch back to water.
2. Find the column that shows the concentration of hydronium ion.
3. Fill in this concentration in the data table.
4. Use a calculator and plug in -log(concetration of hydronium ion) and record your answer in the data table.

What is the relationship between -log (concentration of hydronium ion) and pH?

Switch to the conductivity tester (lightbulb) in the tools. Use it to test the conductivity of each of the solutions. Fill in the data table below to tell if each solution has a conductivity that is low, medium, or high.
