The salt of which one of the follwing five weak acid will be the most hydrolysed?
a. `HA : K_(a) = 1 xx 10^(-8)` b. `HB : K_(a) = 2 xx 10^(-6)`
c. `HC : K_(a) = 3 xx 10^(-8)` d. `HD: K_(a) = 4 xx 10^(-10)`
e. `HE : K_(a) = 1 xx 10^(-7)`

Explanation

To determine which salt of the given weak acids will be the most hydrolyzed, we need to analyze the \( K_a \) values of each weak acid. The hydrolysis of a salt is related to the strength of its conjugate base, which can be determined using the relationship between \( K_a \) and \( K_b \).

### Step-by-Step Solution:

1. **Understanding Hydrolysis**: The hydrolysis of a salt occurs when the salt dissociates in water to form its constituent ions. The extent of hydrolysis depends on the strength of the conjugate base of the weak acid from which the salt is derived.

2. **Using the Relationship**: The relationship between \( K_a \) (acid dissociation constant) and \( K_b \) (base dissociation constant) is given by:
