Hello,

nice to meet you! We are studying the chalcogens at school. I should prove (show) the acid nature of [itex]H_2S[/itex] by writing two chemical interactions.

I am really sorry if the terms I am using aren't the right ones. It's the first time I've ever used this part of the language. Which reactions should I write, and why? Thank you in advance!

Hint - sodium hydrogen sulfide, sodium sulfide
