The hydrate salt `Na_2 CO_3.xH_2O` undergoes `63%`loss in mass on heating and becomes anhydrous. The value of `x` is :

10 grams of a hydrated sodium carbonate, Na_(2)CO_(3).xH_(2)O , on strong heating loses a weight of 6.29 grams. Report the value of x.

0.70 g of a sample of Na_(2)CO_(3).xH_(2)O were dissolved in water and the volume was made to 100 ml. 20 ml of this solution required 19.8 ml of (N/10) HCl for complete neutralisation. The value of x is

Write the use of Na_(2)CO_(3) in laundries ?

On heating 1.763 g of hydrated BaCl_(2).nH_(2)O to dryness, 1.505 g of anhydrous salt remaind. What is the value of n (Mol wt of BaCl_(2)=208 )

The formula of Gibsite is Al_(2)O_(3), xH_(2)O there 'x' is

Na_(2)CO_(3).10H_(2)O when exposed to air looses water of crystallisation and gives finally

The formula of a hydrated salt of barium is BaCl_(2). xH_(2)O If 1.936g of this compound gives 1.846 g of anhydrous BaSO_4 upon treatment with H_(2)SO_(4) calculate x.

Sea water contains small quantities of MgCl_(2) and MgS_(4) Sea water is treated with slaked limeto precipitate the dissolved salty as Mg(OH)_(2) The Mg(OH)_(2) is dissolved in a little quantity of HCI and MgCl_(2)6H_(2)O is crystallised from solution. The hydrated MgCl_(2) is heated in a current of dry HCl gas to get anhydrous MgCl_(2) Pused anhydrous MgCl_(2) is subjected to electrolysis. Magnesium deposited at cathode. In the Hanging method magnesia is a reved by using
