Ionic compounds are formed by the bonding of non-metals to metals. Because inonic bonds involve electon transfer, the result is a mixture of ions; positive and negative, following the laws of electrostatics, like charges attract. These ions then form a giant structure (lattice) of ionic bonds and it is because of this that ionic compounds are solids (unless dissolved in water) and have extremely high melting and boling temparatures. In additions, beucase of the fixed placement of ions (charged particles) in a lattice, in the solid state ionic compounds don't conduct electricity very well but if dissolved in water (aqueous solution) the ions are free to move and carry a current.
Maybe use flash cards for them to understand or look up periodic table on line and show them.
The balanced redox reaction are given below
2CrO₂⁻(aq) + 2H₂O(l) + 6ClO⁻(aq) →2CrO₄²⁻(aq) + 3Cl₂(g) + 4OH⁻(aq)
The Cl species is oxidizing agent .
There are following steps involve in balanced redox reaction in basic medium .
- Divide the reaction into two half reactions .
- Balance the elements other than oxygen and hydrogen .
- Balance the oxygen atom by adding
.
- Balance the hydrogen atom by adding
.
- Balance the charge by adding
. - Add
on both side - Neutralize by combing
and
.
- Add the half reaction and simply .
The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .
