How do I make water fizzy without carbonation?

AI Thread Summary
The discussion centers on the quest for a non-toxic gas that can carbonate water while increasing its alkalinity. Carbon dioxide (CO2) is commonly used for carbonation but makes water more acidic due to the formation of carbonic acid. Participants explore alternatives like nitrogen (N2), which does not affect pH levels but also does not increase alkalinity. Other gases, such as sulfur hexafluoride and xenon, are mentioned, but their low solubility and potential effects limit their practicality. The conversation highlights the complexity of pH in aqueous solutions, emphasizing that pH is dependent on the concentration of dissolved substances rather than the chemical formula alone. Understanding the interaction between gases and water is crucial for achieving the desired taste and pH balance in beverages.

I have had seltzer water which is merely carbonated water which is more acidic hence a more sour flavor as shown in link below. Is there a non-toxic gas that can be added to water to give it bubbles that actually makes it more alkaline? And if so, perhaps combining it with carbonation so the PH is something like 7.2 and tastes like normal water?

https://www.mcgill.ca/oss/article/h...ge for all cold, carbonated water's pH is 4.5.

A short list of gas solubility in water is at:
https://www.wiredchemist.com/chemistry/data/solubilities-gases

Unfortunately, the higher solubility gases on the list are not compatible with life.

If you want a longer list, look here for 7 pages worth:
https://hbcp.chemnetbase.com/faces/documents/05_30/05_30_0001.xhtml

Or if you have access to the CRC HANDBOOK OF CHEMISTRY and PHYSICS
check the Index for: Gases, solubility on water.

Carbon dioxide has no PH because it's a gas? How is it known how a gas effects PH of water when desolved?

When CO2 is dissolved in water, some of it combines with water molecules to make a carbonic acid:
CO2 + H2O --> H2CO3
In water CO2 is very involved with pH.
This in important in biology as well as water quality for fish.

I want more OH than H ions? I assume the above includes 2 H and zero OH?

Do you understand ionization in water?
Here is a review of pH for you.
Do you by chance have a table of chemical formulas and their respective PH level so I can visualize it better?
 
I think baking soda can be used to neutralize acid, but not sure if it adds flavor.

pH is a property of a aqueous solution. The pH of a "chemical formula" doesn't make sense, it is a function of the concentration of a given solute.

Sulfur hexafluoride is one non-toxic gas, but it seems to have too low water solubility for this purpose. Xenon gas is more water-soluble than other noble gases, but I'm not sure how much more of it can be dissolved in water with reasonable pressurization. It is also expensive and has a general anesthetic effect if inhaled in large amounts.

Some gaseous chlorofluorocarbons are likely to be water soluble, but they harm the ozone layer.

Nitrogen is used to "carbonate" drinks without using CO2 carbonation.
Using CO2 makes the water it is dissolved in more acidic. Nitrogen (N2) does not do this, so it doesn't make the water more acidic, but it doesn't make the water more alkaline either. No effect on the pH since it doesn't ionize.

This has been used in several beverage products and has produced flavorful effects:
In soft drinks, sparkling water, beer, wine, juice drinks, tea, flavored water, sports drinks and many other carbonated and non-carbonated beverages, nitrogen provides unique functionality to reduce foaming, protect flavors, retain desired colors, and maintain the integrity of your product.

So I wouldn't be able to look at a formula for a substance and calculate how acidic it is?

You need the properties of the substance when dissolved in water. The substance alone will not be very informative.

You also don't seem to have a very good understanding of the interrelationships between pH, water, and ionized compounds. This will make the success of any calculations you try hit or miss.
Without understanding, mistakes are more likely.

Strange that I hadn't heard about that before...

Hmm. No easy task I guess.
