A dissolved solute that does not form ions is:

• a nonelectrolyte
• a weak electrolyte
• a strong electrolyte
• insoluble

This lightbulb are placed into a beaker containing an aqueous solution and it glows brightly. From this observation, you can conclude the solution is probably —

• The solution is a strong electrolyte and dissociated fully

• The solution is a weak electrolyte and dissociated fully

• The solution is a non-electrolyte and dissociated fully

• The solution is kool-aid

What is a solute?

• The substance that does the dissolving in a solution.
• The substance that is dissolved into the solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

The substance in which something else dissolves is ... (aka the dissolver)

• Solute

• Solvent

• Colloid

• Solution
