Popular questions
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.
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.
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.
What is the formula for potassium hydroxide?
KOH.
How magnesium hydroxide works?
It works as a sparingly soluble base that releases hydroxide ions to neutralize acids and raise pH. In medicinal use it neutralizes gastric acid and, at higher doses, draws water into the intestines to promote bowel movements.
Is magnesium hydroxide safe?
Yes—at permitted food-use levels (E528) it is considered safe by regulators. High intakes can cause diarrhea, and people with kidney impairment should avoid excessive magnesium exposure.
Is magnesium hydroxide a strong base?
Chemically it’s a strong base, but its very low solubility means its aqueous solutions are only moderately alkaline compared with highly soluble bases like sodium hydroxide.
What is magnesium hydroxide used for?
In foods it’s used as an acidity regulator/alkalizing agent and processing aid to control pH. Outside foods it’s the active ingredient in some antacids (milk of magnesia) and osmotic laxatives.
What does magnesium hydroxide do?
In food products it neutralizes excess acidity and helps stabilize pH. Medically it relieves heartburn by neutralizing stomach acid and, at higher doses, promotes bowel movements by drawing water into the gut.
