6.3 Guided Reading Name:
“Acids, Bases, & pH”
1) Foods taste sour because of . Lemons and limes contain acid and dill pickles contain acid.
2) Acids donate a hydrogen ion to form ions when they are dissolved in .
3) You can use an indicator such as to determine if a substance is an acid. If it is an acid it will turn blue paper .
4) Concentrated acids can your skin. They must be used with care and if possible only work with acids.
5) Acids can conduct when dissolved in water because they produce hydronium ions. acid conducts electricity well because it fully in water.
6) The move in water to conduct electricity. A solution of acid in water conducts electricity in car .
7) Acetic acid is a acid and does not conduct electricity well. Not all of the acid to form ions. With fewer ions it does not electricity well.
8) All bases share common properties. Foods that contain bases taste and they are .
9) Bases either contain a ion or will react with water molecules to form ions. Bases turn red litmus paper .
10) hydroxide is a base found in cleaner. It conducts electricity well because it is a base. In water it disassociates to form ions.
11) is a base that does not contain a ion. When it is dissolved in water is gains a ion. This solution does not conduct electricity well because it has dissolved ions.
12) pH is a measurement of the concentration of ions. It determines how , , or neutral a substance is.
13) An abnormal pH in a persons blood is a sign of problems.
14) The pH of a solution ranges from to . Neutral solutions have a pH of and the concentration of hydronium and hydroxide ions is .
15) Solution is a pH of less than 7 are and solutions greater than 7 are . In basic solutions the concentration of hydroxide ions is than the concentration of hydronium.
16) Each unit of pH represents a factor of in hydronium concentration. If there is a pH difference of 2 units a solution is really times more acidic or basic.
17) A strong acid will completely and a strong base will completely. If an acid and basic solutions of equal concentration and volume combine they will form and .
18) Salts are compounds and are in water.
19) The pH of the solution produced depends on the of acids and bases combined and whether they are or .
20) If a acid reacts with an equal amount of a base only some of the acid will be .
21) It takes of a weak acid to neutralize a base.
