Which of the following statements are correct for van't Hoff factor `'i'` for a solution of weak electrolyte `A_(x)B_(y)`?

Options

A. `alpha=1-a+Xa+Ya`
B. `igt1` at normal dilution
C. `i` increases more rapidly with dilution and attains a limiting value of `(x+y)`
D. The increaes in `'i'` with dilution is due to increase in molality of solution with dilution

Explanation

To determine which statements are correct regarding the van't Hoff factor \( i \) for a solution of the weak electrolyte \( A_xB_y \), we can analyze the dissociation of the compound and the implications for \( i \).

### Step-by-Step Solution:

1. **Understanding the Dissociation of Weak Electrolyte**:
- The weak electrolyte \( A_xB_y \) dissociates in solution according to the reaction:
\[
A_xB_y \rightleftharpoons xA^+ + yB^-
