25.1 Acids, Bases, and pH Acids Strong
Acids Weak Acids Properties examples
Def hydrogen ion (H) donor Dissociate in
water COMPLETELY Dissociate a little in water,
reaches equilibrium sour, react w/bases to form
salts and H2O Lemons, oranges, vinegar, stomach
acid (HCl)
3
Bases Strong Bases Weak Bases Properties examp
les
Def hydoxyl ion or hydroxide ion (OH-)
donor Dissociate in water COMPLETELY Dissociate
a little in water, reaches equilibrium bitter,
feels slippery, react w/acids to form salts and
H2O soap, ammonia, cleaners, baking soda, Tums
antacid
4
Acid/Base Chemistry Neutralization
water dissociates/ionizes 2H2O ? H3O OH- (?
means in equilibrium, going back and
forth) (H3O is Hydronium Ion) neutral pH7 ex.
pure water neutralize an acidadd a
base neutralize a baseadd an acid H3O OH- ?
2H2O
5
electrolytes ex. non-electrolytes ex
chemicals that conduct a current when dissolved
in water these compounds form ions, ions conduct
electricity salt water, Gatorade, acids, bases,
tap water Chemicals that do not form ions in
solution, so dont conduct electricity sugar in
water, pure water, ethanol, methanol
