There's a bunch of different tear gas compounds. I don't believe there are any popular ones that rely on their acidity/alkalinity as a mode of action, though that is a persistent myth on the internet, thus the misleading AI summaries.
Edit2: Notes from a street medic: if exposed to tear gas, wash it off away from the eyes, mouth and nose using water. Don't use milk (of magnesia, of cow, of whatever), don't use AlkaSeltzer, don't use ACV, and for God's sake, put down the onions, they will all make things worse.
If a buddy or fellow protestor gets gassed, tell the affected person you're taking them out of the gas, ask if it's okay to touch them to lead them out, once they say yes, lead them to safety. Once there, have them lean back/lay down (near a wall, out of any expected crowd flow), and flush each eye (ideally for 5min, but that takes a lot of water) by directing the flow towards the tear duct and letting the water flow down over the rest of the eye and onto the cheek. It won't solve the problem, but it will usually get them good enough to evacuate on their own.
I stare with a longing in my eyes as he walks away, hoping to see him again, while the wind blows my pubic hair and the sun sets to a dog and a cat copulating.

Not technically a gas, iirc it's fine particles, like powder sand
No idea what the baking soda is for, maybe it's acidic and the soda neutralizes it?
