Question

Select the correct option regarding strong acid.

• A. $E^0$ is positive
• B. $\Delta$S is negative
• C. $\Delta$G is positive
• D. $K_{aq}$ is greater than 1
• E. $K_a$ is very large

Answer 1

The correct option is E $K_a$ is very large

An acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution.
Larger the value of $K_a$ stronger the acidic strength.
Whereas lesser the value of $p{K}_a$ stronger the acidic strength.
