Popular questions
  1. What is the formula of potassium bisulphate?

    KHSO4 (potassium hydrogen sulphate).

  2. Why are there differences in the solubility of calcium chloride and of potassium bisulphate?

    Because their ions differ in charge, size and hydration: CaCl2 has very favorable hydration enthalpy (Ca2+ and Cl−), making it highly soluble and hygroscopic, while for KHSO4 the larger HSO4− anion and hydrogen-bonded crystal structure make the overall balance of lattice energy vs hydration less favorable, so it dissolves less readily (also varying with pH and temperature).

  1. Is potassium hydroxide a strong base?

    Yes—potassium hydroxide (KOH) is a prototypical strong base that fully dissociates in water and is highly caustic in concentrated form.

  2. What is potassium hydroxide used for?

    In foods (E525) it’s used as an acidity/pH regulator and processing aid, e.g., for lye peeling of fruits and vegetables, curing olives, and in some cocoa and caramel color processing.

  3. Is potassium hydroxide safe?

    Yes—at permitted food-use levels it’s considered safe (GRAS in the U.S. and authorized in the EU); concentrated solutions are corrosive and must be handled carefully.

  4. What is the formula for potassium hydroxide?

    KOH.
