Answer: The salt which has the highest pH is
Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:
The given salts are formed from the reaction of acids and bases.
1)
This is a salt formed by the reaction of strong base (KOH) and strong acid . So, this salt is a neutral salt.
2)
This is a salt which is formed by the reaction of weak base and strong acid
. So, this salt is an acidic salt.
3)
This is a salt which is formed by the reaction of weak base and strong acid (HCl). So, this salt is an acidic salt.
4)
This is a salt which is formed by the reaction of strong base (NaOH) and weak acid . So, this salt is a basic salt.
Now, we have to find the salt which has the highest pH value.
Highest pH value means that the salt must be basic in nature and from the given salts, only is basic salt. Hence, this salt has the highest pH value.
Answer :
Dipole moments occur when there is a separation of charge. Dipole moments occur due to atoms electronegativity, where one atom has the ability to attract electrons towards it giving it a negative charge and the one deficient in electrons acquire a positive charge called as the bond moment.
But if the bond moments are equal and opposite in direction , they cancel each other and thus there is no net dipole moment in the molecule.
For example: In carbon dioxide , both the -C=O bonds are polar but as the molecule is linear and the the magnetic moments are equal and oppposite, they cancel each other and the molecule is non polar.
