Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl).

Webb19 jan. 2024 · Potassium carbonate. DrugBank Accession Number. DB13977. Background. Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide's absorbent reaction with carbon dioxide. It presents a large capacity to absorb moisture. 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.
