Potassium Carbonate: Structure, Properties & Uses of K2CO3

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. WebbStart by writing what happens to the salt when you dissolve it. One ionization step is enough; the pH is very high, near one K. The 2nd step is negligible. I bet the teacher wants 2 ICE boxes, not one. Plus, I'm getting 2 unknowns. I think I'm missing something. Inverse log -11.90 = [H=]. All the salt dissolves. havilah ravula
