Acid-Base Reactions (4.2.2)

Question 1

• Arrhenius acids increase H+ concentration in a solution; strong acids dissociate completely in water, whereas weak acids dissociate only partially.

Answer 1

• Arrhenius acids increase H+ concentration in a solution; strong acids dissociate completely in water, whereas weak acids dissociate only partially.

Question 2

• Arrhenius bases increase OH– concentration in a solution; strong bases dissociate completely in water, whereas weak bases dissociate only partially.

Answer 2

• Arrhenius bases increase OH–

concentration in a solution; strong bases dissociate completely in water, whereas weak bases dissociate only partially.

Question 3

• A Lewis acid or base does not have to contain H+

or OH–- but it will still generate these ions in water.

Answer 3

• A Lewis acid or base does not have to contain H+

or OH–- but it will still generate these ions in water.

Question 4

• A pH indicator changes color with changing amounts of H+ or OH– ions and can be used to demonstrate that acids and bases react together in a neutralization
reaction to form water and a salt.

Answer 4

• A pH indicator changes color with changing amounts of H+ or OH– ions and can be used to demonstrate that acids and bases react together in a neutralization
reaction to form water and a salt.
