How can I test if a mixture I have contains ethanol or isopropyl (mixture is 70% alcohol and 30% purified water)? Will a simple "salting out expuriment" work (seeing if the mixture separated with salt or not)? Or is there a better way to check it?

Is 70% isopropyl (with the other 30% being purified water) good enough (even if it burns weaker than 90% isopropyl)?

I recently bought a home chemistry lab and I need to use denatured alcohol for the burner. 1. What type of alcohol is best suited for this (ethyl alcohol, isopropyl, etc.)? And after buying the alcohol what would be the best and safest way to store it without worrying about the flammable vapors in my house
