false
t/f: an aqueous solution of acids causes red litmus paper to turn blue.
false
t/f: an acidic solution contains more hydroxide ions than hydrogen ions.
true
t/f: acids add flavor to many beverages and foods.
false
t/f: acid solutions taste bitter and basic solutions taste sour.
true
t/f: acids and bases have the ability to conduct electricity.
true
t/f: the relative amounts of hydrogen and hydroxide ions determine whether an aqueous solution is acidic, basic or neutral.
false
t/f: a conjugate acid is produced when an acid accepts a hydrogen ion.
true
t/f: substances that can act both an acid and a base are said to be amphoteric.
false
t/f: the Arrhenius model states that acids and bases share electron pairs.
false
t/f: An acid is an ion or molecule with a lone electron pair tat it can donate or share.
false
t/f: an acid anhydride is an oxide that can combine with water to form a base.
false
t/f: conjugate acid and bases react to form Bronsted- Lowry acids and bases.
true
t/f: in solution, strong acids and bases ionize completely, but weak acids and bases ionize only partially.
true
t/f: a single arrow in a reaction means that the reaction goes to completion.
true
t/f: weak acids produce fewer ions than strong acids and cannot conduct electricity as well.
false
t/f: in a typical reaction, if the reacting acid is strong, the base produced is strong.
false
t/f: An aqueous solution of acids causes red litmus paper to turn blue.
false
t/f: a neutral solution contains more hydroxide ion than hydrogen ions.
