Electrolytes,pH Scale, & Electrolytic Dissociation Flashcards
What is a electrolyte?
An electrolyte is a substance ( when did soy in water ) allows an electric electricity to flow through.
What are nonelectrolytes ?
Nonelectroyles is a substance that dissolves in water but didn’t conduct electricity
What happens when an electrolyte is dissolved in water ?
When an electrolyte is dissolved in water it separates into two ions ( 1positive and 1negative )
What is electrolytic dissociation?
Electrolytic dissociation Is when a electrolyte is dissolved in water, and separates into two ions (1positive and 1negative)
When electrodes are put in water, the negative electrode will attract the ____ ions
The negative electrode will attract the positive ions
When electrodes are put in water, the positive electrode will attract the ____ ions
The positive electrode will attract the negative ions
When electrodes are inserted into a solution is generates what?
When electrodes are inserted into a solution is generates an electric current.
What is the strength of an electrolyte determined by ?
It’s determined by the degree of dissociation
A pH scale from 0-6 is a ___
Acid
A pH scale from 8-14 is a _____
Base
A pH of 7 is a ____
Neutral
What color does Acids turn blue litmus paper ?
Red
What color does Bases turn blue litmus paper ?
Blue
What color does Acids turn red litmus paper ?
Red
What color does Bases turn red litmus paper ?
Blue
All acid chemical formulas begin with __ ?
H
Why do all acid chemical formulas start with H ?
It’s because all acids release H(Hydrogen) ions when in an aqueous solution (when dissolved in water) . In addition acids also release a negative ion, which most of the time is a nonmetal.
Are acids electrolytes ?
Yes
Are bases electrolytes ?
Yes
All base chemical formulas end with __
OH
Why do all base chemical formulas end with OH ?
It’s because all bases release OH ions when in an aqueous solution. They also release positive ion ( most of the time )
What color does Salts turn red litmus paper ?
Red
What color does Salts turn blue litmus paper ?
Blue
Salts are made up of ___?
A metal and a nonmetal
Salts release what ions in a aqueous solution?
A positive ion ( by metal ) and a negative ion ( by nonmetal )
Are salted electrolytes ?
Yes
