WebbH2CO3 is considered an acid because it ionizes in H+ and HCO3-. Some of the HCO3- will bond with water and form OH- and H2CO3 again. This is an equilibrium. But If we have only one HCO3- that didn't yet bonded to water and formed H2CO3 again, we will have more H+ in the medium, and it will be acid. Webb10 feb. 2024 · Ok, as a test I tried targeting ~1.3 KH with 330 mg of K2CO3 in 10 liters of RO water. That gave me a pH around 7.5, which is reasonably consistent with the math @dw1305 pointed to above, so for tomorrows WC's I think I will just target that and should give me 18 ppm of K as well ... this should work out.
