Answer: Option (D) is the correct answer.
Step-by-step explanation:
Bases are the substances that release hydroxide ions when dissolved in water.
A strong base will dissociate completely in water and give more number of hydroxide ions
. Whereas a weak base will slightly dissolve to give hydroxide ions
in water.
So, a strong base will have high electrical conductivity and a weak base will have low electrical conductivity.
Since, both are bases (strong base and weak base) therefore, both of them will have bitter taste, slippery texture and they will turn red litmus into blue.
Hence, we can conclude that electrical conductivity tests could be safely used to distinguish a strong base from a weak base.
