| Very poorly executed.
No one is going to guess "Most". "Group 1" and "Group 2" seem valid, as does "NH+", although like most Sporcle quizzes, guessing one of those broader definitions should be acceptable (such as accepting "Sodium" for Group 1 or "Magnesium" for Group 2)
Anyone with basic chemistry knowledge should know that everything is soluble with nitrates, so that's valid. Really, the only thing in need of fixing is "Most". Either get more specific with the answer or accept partial answers (like I said with Groups 1 and 2). |
