To tell if Na2SO4 (Sodium sulfate) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed Na2SO4 . First...
Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na2SO4 + BaCl2 → 2 NaCl + BaSO4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.
Sodium sulfate is the sodium salt of sulfuric acid. With an annual production of 6 million tonnes, it is one of the world's major commodity chemicals. Anhydrous, it is a white crystalline solid of formula Na 2 SO 4; the decahydrate Na 2 SO 4 ·10H 2 O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century.
We can determine whether a salt solution will be acidic, basic, or neutral by considering the reactivity of both the cation and the anion with water. If neither species reacts with water, the solution will be neutral.
12 Ιουλ 2019 · In a solution of a salt formed by the reaction of a weak acid and a weak base, to predict the pH, we must know both the K a of the weak acid and the K b of the weak base. If K a > K b , the solution is acidic, and if K b > K a , the solution is basic.
Sodium sulfate is the sodium salt of sulfuric acid and has different forms depending on the water of crystallisation. It is used as a drying agent, a laxative, a glass fining agent, and in many other applications.
A salt can dissolve in water to produce a neutral, a basic, or an acidic solution, depending on whether it contains the conjugate base of a weak acid as the anion (\(A^−\)), the conjugate acid of a weak base as the cation (\(BH^+\)), or both.
