When concentrated `H_(2)SO_(4)` is added to NaCl solid,then HCl gas is liberated because

What happens when (i) Concentrated H_2 SO_4 is added to calcium fluoride. (ii) SO_3 is passed through water ?

What happens when (i) Concentrated H_2 SO_4 is added to calcium fluoride. (ii) SO_3 is passed through water ?

When dilute H_(2)SO_(4) is electrolyzed between Pt electrodes, the gas liberated at the anode will be ………………………….

concentrated H_2 SO_4 can be used to dry which gas ?

A liquid was mixed with ethanol and a drop of concentrated H_(2) SO_(4) was added. A compound with a fruity smell was formed. The liquid was

A liquid was mixed with ethanol and a drop of concentrated H_(2) SO_(4) was added. A compound with a fruity smell was formed. The liquid was

H_(2)SO_(4)+NaCl(s)rarrNaHSO_(4)+HCl . Hydrochloric acid is liberated because

An inorganic salt when heated with concentrated H_(2)SO_(4) evolves a colourless pungent smelling gas but with concentrated H_(2)SO_(4) and MnO_(2) evolves a coloured pungent smelling gas which bleaches moist litmus paper.The coloured gas is:

A colourless (A) when place into water a heavy white turbidly of (B) solid (A) gives a close solution in conesolution in cone HCI when HCI solution is added to clear solution water ,(B) forms again (B) dissolves in dilute HCI . When H_(2)S is passed through a sespension of (A) or (B), a black precipitate (C ) forms , (C ) is insolves in yellow ammonium sulphide (NH_(4))_(2)S , cone H_(2)SO_(4) added to solid (A) liberates gas (D) gas (D) is water soluble and gives white precipitate with mercuric salts (E ) and not mercuric salt .The black precipitate (C ) dissolves in HNO_(3), (1,1) to give a solution to which H_(2)SO_(4) is added followed by addition of NH_(4)OH when a white precipitate (F) is formed (E ) gives a black ppt , (G) with solution of sodium stannite. Compound (C ) is also formed by the following reaction
