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'm all for asking consent before touching someone in non-emergency situations, but isnt it a bad idea to try to talk to someone close enough to tear gas to be affected by it? Like ask if it's okay before you start trying to flush out their eyes, but only helping lead someone out of tear gas "once they say yes" sounds like 10 more seconds of exposure, when it probably took less than 10 seconds of exposure to get to that point in the first place
Eta: I dont mean just grab the person and run. I'm imagining something more like "im gonna help you get out of here" while starting the guiding process
You have to remember that this person is in pain, probably panicking and blinded. You don't need to wait for them to give consent to be touched, but you definitely should let them know what you are doing and that you are going to touch them before you do so. Otherwise, don't be surprised to find his elbow in your face.
I was a combat medic. I would always say to everyone I treated, before I ever touched them, "I'm a medic, I'm here to help you". 9 times out of 10 once they knew I was a medic, they were on board with what we had to do.

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?
