Yes, except don’t do this.
The reaction is
NaHCO~3~ + CH~3~COOH -> Na^+^ + CH3COO^-^ + + H~2~O + CO~2~
If you know how to read those. Sure the CO2 is the same if you let the vessel pressurise but that sodium ion and ethanoate isn’t! Sodium salts taste well very salty. It’ll ruin the lemonade
oh sorry brain fart, replace ethanoic acid with critic, same difference really it’ll still be salty. I thought you meant adding vinegar and bicard like highschool science to make co2.
If you want though you can generate the co2 that way separately and pump the gas into the lemonade. That’ll not ruin the flavour

I appreciate all of this chemistry trivia ❤️
Edit my comment? Erase my mistake?
Tell me young one, can a man be unkilled? a lie untold? a promise unbroken?
Nay, I have done a fell thing and shall wear the stain of it forever.
I assumed you a chemist, what a blunder.
Clearly you’re a warrior poet with a passion for chemistry.
Actually adding baking soda and an acid to drinks is a fairly well traveled (and old fashioned) means of carbonating them. The contribution of the Sodium to the taste of the drink usually isn’t very high and adding sugar further reduces its effects.
Really? But to get decent carbonation you would need to add a lot. Like 15 grams or so because dissolution is not very efficient, most the co2 is going to pressurise the headspace
The amount required depends on the volume being carbonates. 1L of CO2 requires about 3.5 grams of Sodium bicarbonate which is about a teaspoon. I use Potassium bicarbonate (usually used in home brewing for controlling pH) instead because 1) it works just as well and 2) it boosts the amount of Potassium rather than Sodium in my diet. As for headspace, you only leave enough that the reaction doesnt cause the contents to splatter everywhere before you can recap the bottle. The contents should be sweet enough that it doesnt matter if theres a couple grams of a Sodium or Potassium salt mixed in which isnt hard to do if you use a reasonable amount of sweetener eg. table sugar, fruit juice, stevia etc.
Fair enough, I don’t drink many sweet drinks and tried to carbonate soda water that way.
Re head space, you also need to make sure you’re leaving enough when you open it. You’re only very lightly carbonating with 3.5 g. Most soda water and softdrinks have a head pressure of around 70 psi, the bottles can actually spike to around 150 when dropped which is sort of terrifying. Without the addition of all the crap they add to slow nucleation bottles can erupt very merily when opened!
When making my own soda water (I just hook bottles up to a regulated stream of co2 and shake) I do actually add some but only about 1/8 of a teaspoon per litre.
Making things slightly salty makes them nice and I find it helps reduce some of the harsh acid taste the carboxylic acid. Also it seems to modify how the bubbles form which is interesting. Maybe a surface tension of water effect? I’m unsure there.

Good point Salty lemonade does not sound very nice.

Yeah I tried this once as a kid haha. You neutralise a bunch of the acid so it isn’t crisp and sharp, instead it tastes like mildly lemon salt.
