Intro to Acids and bases

An acid

• is a substance that releases H+ ions when dissolved in water

• is a substance that does not release any ions when dissolved in water

• is a substance that releases OH- when dissolved in water

• releases an equal amount of OH- and H+ ions when dissolved in water

Which of these solutions is an acid?

• Dish Soap: pH of 12

• Tomato Soup: pH of 4

• Baking Soda: pH of 9

• Drain Cleaner: pH of 14

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

• Acidic
• Basic
• Neutral
• Tasty

The pH scale is a range from:

• 1-7
• 0-14
• 1-5
• 1-20

When dissolved in water, bases produce:

• acids
• salts
• hydrogen ions
• hydroxide ions

A  pH and a pOH will add up to:

• 0
• 7
• 14
• 1.0 x 10^-14

Water has a neutral because

• it has more H+ ions than OH-

• it has more OH- ions than H+

• it does not produce any ions

• it has an equal amount of H+ and OH- in solution

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

The pH of a solution is tested, and it is found to be a basic solution. Of the following choices, what could the pH have been?

• 3
• 9
• 7
• 5

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6
