ok so i had to identify the unknown compound, which actually for me was Sodium carbonate. i dont know if i did this correctly because there was alot of confusion with my lab partner (screwed me big time, couldnt even count drops; i will be getting a new lab partner next week!) and time constraints i wasnt able to finish it up. I asked the prof if i could repeat it and ofcourse, she said no. just ignore the unknown compound section, but is the rest of it correct?

i was supposed to find out whether the reaction is a gas, precipitate appears or disappears, or if the color changes.

and this is the complete lab
