Exit Review: 5/13-14

The pH scale is a range from:

• 1-7
• 0-14
• 1-5
• 1-20

A base is a substance

• That releases OH- ions when dissolved in water

• That releases H+ ions when dissolved in water

• Does not release any ions when dissolved in water

• None of the above

A solution has a pH of 7.0.  What would happen to the pH if OH ions were added?

• pH would go up
• pH would go down
• pH would stay the same
• None of these

If the [H+] of a solution is 1 x 10^-2 mol/L the pH is

• 2
• 12
• -2
• 1

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

A  pH and a pOH will add up to:

• 0
• 7
• 14
• 1.0 x 10^-14

If the [OH-] of a solution is 2.7 x 10^-4 mol/L the pOH of the solution is

• 10.44
• 3.56
• 1.00
• -4.43

If the pH of a solution is 7 the solution is said to be

• Acidic
• Basic
• Neutral
• Tasty

Al(OH)₃

• Acid
• Base

HNO₃

• Acid
• Base
