I got an easy cation unknown solution!!!!!!!!!!!!

The separation of the known solution took like two and a half hours, but the unknown solution took about 2 and a half minutes. It was so cool! Iron, zinc, silver, barium and copper could've been in my unknown but only about 2-4 of them were really supposed to be present. I got a colorless unknown which meant I didn't have iron or copper. Two down. I added HCl to test for silver and nothing! Two left. Hmm...I wonder what cations are in my solution. I got a perfect! AND I got out an hour early. Happy!!!!!
