Electrolytes

What state of matter is an electrolyte?

• solid

• gas

• plasma

• aqueous

What is required for a liquid to conduct an electric current?

• ions that are mobile

• ions in a strong bond

• covalent bonds

• shared protons

Why are all ionic compounds electrolytes?

• because they are non-metals

• because they share electrons when they bond

• because they are electrically neutral

• because they dissociate into ions

Some chemical compounds are weak electrolytes. Why?

• they are made of soft metals, instead of tough metals like iron

• they have nonpolar bonds that cannot be broken
