Sodium borate is a salt of strong base (NaOH) and weak acid (H3BO3). Hence, its aqueous solution will be basic.

1. Sodium borate is a salt of strong base (NaOH) and weak acid (H3BO3).
2. Its aqueous solution will be basic.
3. NaOH is a strong base.
4. H3BO3 is a weak acid.

Correct answer: Its aqueous solution will be basic.

Solution

Sodium borate, being a salt of a strong base (NaOH) and a weak acid (H3BO3), hydrolyzes in water to produce OH⁻ ions, making the solution basic.
