Although the exact carbonation constant is 2, it’s safer to add a slightly higher amount of carbonation, so
I’ve set the default carbonation constant to 3.
I’ve set the default carbonation constant to 3.
| Volume of undiluted solution (mL) | mL |
| Carbonation Level (mL) | mL |
| Water (mL) | mL |
Concentrations of sodium hypochlorite (typical examples, transcribed from manufacturers’ websites):
Hypolite M10 10%
Purax-10, Kenmix 10 10%
Purax, Purax-S 6%
Dianoc 6%
Kenmix 4 4%
Kao Hyter, Kitchen Hyter 6%
The manufacturer’s website explicitly states that the concentration at the time of manufacture is approximately 6%.

However, the manufacturer’s preparation instructions list the concentration as 2%.

★☆ WARNING ☆★
Most “hypochlorous acid water generators” sold on online retailers like Amazon are actually “sodium hypochlorite generators.”
Neutralization is required. It is extremely dangerous to mistakenly use them as “hypochlorous acid water.”
Sodium hypochlorite ⇒ Bleach.

I created a handy calculation formula based on the video posted by paxm40.
Mixing sodium hypochlorite with acidic substances may cause chlorine gas to be released. Be sure to perform this in a well-ventilated area.
Also, be sure to use pH and hypochlorite test strips.

This is the calculation formula for making “hypochlorous acid water” from “sodium hypochlorite.”
・Total Volume (L) → The volume of “hypochlorous acid water” you want to make
1 L = 1000 mL
The unit for total volume has been changed from mL to L.Since plastic bottles typically come in sizes of 0.5 L, 1 L, 1.5 L, and 2 L,
・Concentration of stock solution (%) → Concentration of sodium hypochlorite
・Final concentration (ppm) → Concentration of the hypochlorous acid water you wish to produce
1% = 10,000 ppm
