PS1-5: Acids and Bases
Go to the phet simulation and click on introduction.

Click on Water and Molecules, Drag the pH meter into the solution to get the pH reading
Notice the chemical reaction for water. The product H3O+. is the same as an H+ ion. This means a compound with H in front.

The magnifying glass shows the products that form when water breaks down into 2 ions H3O+ (acid) and OH- (base).

Which is true about the solution that forms when water breaks down into it's 2 ions.

Based on your response to question 1, why do you think the pH of this solution is 7 (neutral)?

1

Click on strong acid. What do you notice happens to the solution? Click all that apply

1

Click on weak acid. What do you notice happens to the solution? Click all that apply


1

Click on strong base. What do you notice about the solution?

1

Click on weak base. Compare this to strong base. What's similar and what is different?

1

What do you think the double sided arrow in a chemical reaction means?


1

Why do you think strong acids and bases have a 1 sided arrow and weak acids and bases have a double sided arrow?

Strong acid:


Weak acid:

Click on graph. Play around with the simulation by clicking on strong and weak acids and bases.

What patterns do you notice in the concentrations (amount) of reactant compounds and product ions that form in the solutions.
