Question

1)Name a simple method your employee to prepare ammonium salt in the laboratory.
2)When the vapour of methanol is passed over heated copper II oxide the new organic compound formed is ________.
3)A non metal which has a very high melting point-
4Why a solid ionic compound does not conduct electricity?

Answer 1

1.Ammonium salt like ammonium sulphate can be prepared in the laboratory by neutralising Dil HCl with ammonium sulphate solution.
2.)H-COOH methanal organic compound is formed.
3.)Carbon is the non-metal which has high melting-point.
4.) Because inorder to conduct electricity the compound needs to be in molten aqueous soln. or in fused state.So it is not possible to conduct electricity in hard solid compound because of strong electrostatic force of attraction.
