I need to find out if sucrose, sucrose solution, sodium chloride, sodium chloride solution, water, vinegar, and aluminum are electrolytes and what type of bond they are but I don't know where to look.
You can google ionic bonds, electrolytes, covalent bonds, and get general information but I don't know where you can find all of this "put together" so you can answer the questions.
Here are the answers.
sucrose: covalent bonds (some are polar covalent), solution is non-electrolyte.
NaCl: ionic bond, solution is an electrolyte (a strong electrolyte since it is 100% ionized in solution).
water: polar covalent bonds, essentially non-electrolyte although it ionizes to a very small extent.
vinegar: covalent bonds some of which are polar covalent, weak electrolyte since it is about 1% ionized in 0.1 M solution.
Al is a metal. It conducts electricity very easily and very well. It's a solid, the bond in the metal is a metallic bond, and the term electrolyte doesn't apply (at least in my opinion).
In addition you might want to consider the differences (if any) between solid sodium chloride and molten sodium chloride, soild sucrose and molten sucrose, solid aluminium and molten aluminium.
