The question is incomplete. Complete question is:
<span>Consider the given acid ionization constants. identify the strongest conjugate base.
</span>HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option
4: HCN(aq) 4.9×10−10
Reason:
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.
In present case, ionization constant is highest of HCN i.e. 4.9×

. This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e.

) is the weakest.
Answer:
The answer to your question is below
Explanation:
Physical properties are the properties in which there is no change in the nature of the substance but there is a change in the physical state.
Chemical properties are the properties in which the substance changes its nature. A new substance is formed.
