Acid-Base Reactions (4.2.2) Flashcards
• Arrhenius acids increase H+ concentration in a solution; strong acids dissociate completely in water, whereas weak acids dissociate only partially.
• Arrhenius acids increase H+ concentration in a solution; strong acids dissociate completely in water, whereas weak acids dissociate only partially.
• Arrhenius bases increase OH– concentration in a solution; strong bases dissociate completely in water, whereas weak bases dissociate only partially.
• Arrhenius bases increase OH– concentration in a solution; strong bases dissociate completely in water, whereas weak bases dissociate only partially.
• A Lewis acid or base does not have to contain H+
or OH–- but it will still generate these ions in water.
• A Lewis acid or base does not have to contain H+
or OH–- but it will still generate these ions in water.
• 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.
• 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.
Strong Bases & Acids in Water
Completely Dissolve
Weak Bases & Acids in Water

What is a pH Indicator?
A substance/device that gives a value based on amounts of OH- or H+.
