A hydrated salt, Na 2 SO 4. nH 2 O undergoes 56% loss in weight on heating and become anhydrous. The value of n(approximately) will be : (PLEASE ANSWER IN A EASY TO UNDERSTAND MANNER)
7 Ιουν 2024 · The water of crystallisation is separated from the main formula by a dot when writing the chemical formula of hydrated compounds. E.g. hydrated copper (II) sulfate is CuSO 4∙ 5H 2 O. A compound which doesn’t contain water of crystallisation is called an anhydrous compound. E.g. anhydrous copper (II) sulfate is CuSO 4.
8 Ιουλ 2024 · Here, \( Na2SO4 \) is sodium sulfate and \( nH2O \) represents the water of hydration. Step 2: Calculate the molar mass of the components - The molar mass of \( Na2SO4 \): - Sodium (Na): \( 22.99 \, g/mol \times 2 = 45.98 \, g/mol \) - Sulfur (S): \( 32.07 \, g/mol \) - Oxygen (O): \( 16.00 \, g/mol \times 4 = 64.00 \, g/mol \) Total for ...

1 Ιουν 2019 · The hydrated salt, `Na_(2)SO_(4)*nH_(2)O` undergoes `55.9%` loss in weight on heating and becomes anhydrous. The value of `n` will be: A. `5` B. `3` C. `7` D. `10`
The hydrated salt Na2SO4. nH2O, loses all water of crystallization on heating and is reduced to 44.1 % of its original weight. Therefore, the value of n is. ...
By solving this we will get $ n = 10 $ . The hydrated salt was $ N{a_2}S{O_4}.10{H_2}O $ . So, option D is correct. Note Sodium sulphate is used as a thermal storage.
