Answer:
NaS is ionic compounds that's why it is polar.
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium sulfide is ionic compound. The electronegativity of sulfur is 2.58 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the sulfur. Sodium becomes positive and sulfur becomes negative ion. There are electrostatic fores present between bonded atoms and molecule becomes polar.
Answer : The concentration of the 
is, 0.115 M
Explanation :
Using dilution law,
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of 
= 0.125 M
= concentration of KOH = ?
= volume of = 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the .
Therefore, the concentration of the is, 0.115 M
