Dihydroxyaluminum sodium carbonate এর কাজ, ব্যবহারের নিয়ম

Calcium Carbonate (CaCO3) commonly known as Limestone, Marble, Chalk. 

Solution: weight of metal carbonate/GEW = NaXVa in lt 0.84/GEW = 0.5X40/1000 GEW of metal carbonate = 42 GEW of Metal = 42 - GEW of CO3-2 = 42-30 = 12g

Na atom get oxidize and Cl is reduced

Solvay process cannot be used to prepare potassium carbonate. This is because unlike sodium bicarbonate,potassium bicarbonate is fairly soluble in water and does not precipitate out.

(a) Echinodermata

(i) Sodium oxide                 → Na2O  (ii) Aluminium chloride       → AlCl3  (iii) Sodium suphide           → Na2S  (iv) Magnesium hydroxide → Mg(OH)2

In a reaction, sodium carbonate reacts with ethanoic acid to produce sodium ethanoate, carbondioxide, and water.  Sodium        +       Ethanoic → Sodium      +     ...

A sodium atom and ion, differ by one electron. For 100 moles each of sodium atoms and ions there would be a difference of 100 moles of electrons.  Mass of 100...

Antacids such as sodium hydrogen carbonate, magnesium hydroxide, and aluminium hydroxide work by neutralising the excess hydrochloric acid present in the stomach. However, the root cause for the release of...
