Which equations shows the complete dissociation of a strong base?
2 answers:
Answer : The correct option is, (4)
Explanation :
Strong acid : Strong acids are those acids which are completely dissociates into ions in water. It dissociates into hydrogen ion and an anion.
Strong base : Strong base are those base which are completely dissociates into ions in water. It dissociates into hydroxide ion and a cation.
In all the given options, option (4) equation shows the complete dissociation of a strong base.
While the other options shows the complete dissociation of an acid.

There are four different representations of the orientation of water molecules around chloride anion. Let's first analyze the water molecule.
We have H-O-H as the structure of water. The oxygen atom is more electronegative than the hydrogen atoms, which results in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
The chloride anion is a negative charge. Therefore, the water molecules should orient themselves with the hydrogen atoms facing the chlorine atom as the partial positive charge on the hydrogen atoms will be attracted to the negative charge of the chlorine atom.
The correct representation is shown in graph 3 which shows all hydrogen atoms facing the chlorine anion.
