Well, Cl is highly toxic and reactive, and Na is also highly reactive and explodes with water – so we’re halfway there. Cl- and Na+ behave very differently though and are stable. Hence why saltwater can exist and not blow-up. So… Yeah no boom :(.

But consolation prize, I have a fun story of a demonstration I once did! I was asked in high school to do a chemistry demo for a special ed class, and so I got some sodium and a beaker of crushed ice. When the reaction started, the beaker jumped a foot into the air and exploded. I had put a blast shield up so there wasn’t any safety issue, but there were shards of glass like a yard/meter behind it. It was insane.

… Please don’t go buying Sodium and replicating it at home. I am not responsible for any injuries nor damages.
