The use of common salts, e.g., `NaCl` or `CaCl_(2)` anhydrous, is made to clear snow on the rods. This causes:

A

A lowering in the freezing point of water.

B

A lowering in the melting point of ice.

C

Ice melts at the temperature of atmosphere present at that time.

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
Addition of salt lowers the freezing point of water and thus snow melts.

    0.378 g od an organic compound containing carbon and hydrogen was subjected to cobustion by Liebig's method , the CO_(2) and H_(2)O formed were passed through potash bulbs and CaCl_(2) (anhydrous) tube. At end of the experiment, the increase in the respective weights were 0.264 g and 0.162 g. Calculate the percentage of carbon and hydrogen.

    Read following statement(s) carefully and select the right option : (I) The enthalpy of solution of CaCl_(2). 6H_(2)O in a large volume of water is endothermic to the extent of 3.5 kcal/mol. If DeltaH=-23.2 " kcal" for the reaction, CaCl_(2)(s)+6H_(2)O(l)rarrCaCl_(2).6H_(2)O(s) then heat of solution of CaCl_(2) (anhydrous) in a large volume of water is - 19.7 kcal/mol (II) For the reaction 2Cl(g)rarrCl_(2)(g) , the sign of DeltaH and DeltaS are negative.

    Dow's process of extraction of Mg involves extraction of Mg from sea water. Sea water is concentrated in sun light and is then treated with slaked lime. Magnesium hydroxide is heated in a stream of HCl to give MgCl_(2) which is electrolyzed to discharge Mg. the mixture is in the ratio 35% MgCl_(2) + 50% NaCl + 15% CaCl_(2). NaCl and CaCl_(2) are added to lowr the fusion temperature and to increase the conductance. {:(Mg^(2+) + Ca(OH)_(2) rarr Mg (OH)_(2) + Ca^(2+)),(Mg(OH)_(2) + 2HCl rarr MgCl_(2) + 2H_(2)O(l)),("Electrolysis of fused" MgCl_(2) overset("Anode")rarr 2Cl^(-)rarr Cl_(2) + 2_(-1e^(0))overset("cathode")rarr Mg^(2+) + 2_(-1e^(0)) rarr Mg):} Mg electrolysed is protected from atmospheric oxidation by a blanket of inert gases. Molten mixture of NaCl of CaCl_(2) is added to the heated MgCl_(2).xH_(2)O with dry HCl gas because :

    CaCl_(2) is preffered to NaCl for clearing snow on roads particularly in very cold countries. This is because
