Bad conductor of electricity is: (a) H2F2 (b) HCl (c) HBr (d) HI. In the absence of electrons no solution or water can conduct electricity as ions carry electric charge and conduct electricity. We’re always told and taught that water conducts electricity. Leadership. What are Different Chemical Effects of Electric Current . Options. In solid NaCl, there are charged particles which are the Na+ and Cl- ions, but they aren't able to move as the ions are fixed in the lattice. In ice, the free movement of charge is hindered by the rigidity of the solid structure. When wires are connected to batteries and bulbs, the bulbs light because there is a good conductor making a path for that current. If we compare two types of material and the first one allows better flow of electricity through it, then that material is said to be a good conductor of electricity. (b) Metal are good conductors of electricity because they have free electrons to conduct electricity. 0 votes. K), which makes the diamond five times better at conducting … Bad conductors of heat. This happens mainly due to two reasons: The reactivity of fluorine atom is high as it needs only one electron to fill its outermost orbit. (iii)Resistance also depends on a material of the conductor ∴ R = ρ l A (iv) Resistance and resistivity also depend on temperature. Is Water a Good Conductor of Electricity? It can be clearly seen that each carbon atom in diamond is covalently bonded to four other carbon atoms, leaving no electrons to move freely and since electrical conductivity is due to movement of free electrons, hence diamond is a poor conductor of electricity Bad conductor of electricity is: (a) H2F2 (b) HCl (c) HBr (d) HI. Terms of Service, Chapter 14 Class 8 - Chemical Effects Of Electric Current. The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. All nonmetallic elements are generally poor conductors of heat and electricity. Bad conductors are those materials which do not allow electricity to pass through them easily. Hence, it does not exist as ions. Will electricity follow a path of least resistance on a rotating conductor? Air is a bad conductor of electricity. Addition of few drops of H₂SO₄ makes water impure as it contain sulphate ions along with water, so it will conduct electricity.
