Electrolytes Flashcards
What types of solutions conduct electricity?
Acid, base, salts (neutral)
Metals & non metals bonded together form what in water?
Ions
What substances form ions in water?
Metals & non metals
acids
bases
(IONIC SOLUTIONS)
What happens when compounds are dissolved in water?
Two separate ions (+ and -)
What does ionic mean in greek?
To go
How to identify acids from their formula? Exception?
It starts with H
H+NM
Exception: C6H8O7
How to identify bases from their formula?
It ends with OH
M or TM or Polyatomic & OH-
Electrolytes have the ability to what?
Conduct electrocity
Which of the following substances are electrolytes?
NaOH Co2 NaCl CuSO4 C6H12O6 HCl
NaOH
NaCl
CuSO4
HCl
What type of bonds make electrolytes?
Ionic
Can the strength of electrolytes be compared?
Yes, if the concentration is equal
The strength of electrolytes corresponds to what?
The degree of dissociation of the ions
More dissociation equals what? How does this affect a light bulb?
More ions and thus a stronger electrolyte
The light bulb will thus shine brighter or blink frequently
All electrolytes can be classified as what?
Acids
Bases
Salts
What is litmus paper?
The ultimate tester, but does tell strength (thats pH paper)
Litmus paper reactions and meaning
blue becomes red = acid
red becomes blue = base
red stays red, blue stays blue = neutral
What are electrolytes?
Substances that conduct electricity when dissolved in H2O (in aqueous solution). There are 3 types of electrolytes: acids, bases, and salts (neutral)
