Which of the following statements about HCO_(3)^(-) are correct ? 1.

1.	Which of the following statements about HCO_(3)^(-) are correct ? 1. It is a Bronsted acid 2. It can ionize in water to form CO_(3)^(2-) (aq) 3. It does not exist in aqueous solution 4. It is a Bronsted base. Select the correct answer using the codes given below
Answer» 1, 2 and 3 2, 3 and 4 1, 3 and 4 1, 2 and 4 Solution :`HCO_(3)^(-)` is Bronsted ACID as WELL as Bronsted base because it can proton as well as ACCEPT proton. It can ionize in water to `CO_(3)^(2-)` ion. It can exist in AQUEOUS solution. Hence, only 3 is wrong
