1.           An equation that represents HNO3 acting as an Arrhenius acid. ( including the correct charges for ions!)

2.            An equation that shows magnesium hydroxide, Mg(OH)2, acting as an Arrhenius base.

3.             What are the effects of strong acids and bases on the skin?

4.            Lime juice is quite sour. Which of the following is a reasonable pH for lime juice: 2, 7, 9, or 12?

5.            What is the pH of a solution that has a hydrogen ion concentration of 1.0 x 10-3 M?

6.            Hydrogen bromide (HBr) gas reacts completely with water to form hydronium ions and iodide ions.

a.   Classify HBr as a strong acid, weak acid, weak base, or strong base.

b.   Explain how you know this classification.

c.    Give an equation to demonstrate this reaction.

7.            What is the [H+] of a solution that has a pH of 5.6?

Like water, the hydrogen phosphate ion (HPO42-) is amphiprotic. That is, it can act like a Bronsted-Lowry acid or as a Bronsted-Lowry base. Write equations to show both of these reactions with water.
