Write the formula of the conjugate acid of base HCO3-,HPO2-,PO43-,SO32-
Bases have fewer H atoms; acids have more H atoms.
HCO3^- add a H atom to make H2CO3.
HPO^2- + H^+ ==> H2PO2-
PO4^3- + H^+ ==> HPO4^2-

To determine the formula of the conjugate acid for each of the bases HCO3-, HPO2-, PO43-, and SO32-, we need to add a proton (H+) to each base. Here are the formulas of the conjugate acids:
1. HCO3- (base) -> H2CO3 (conjugate acid)
The formula of the conjugate acid of HCO3- is H2CO3.
2. HPO2- (base) -> H2PO2- (conjugate acid)
The formula of the conjugate acid of HPO2- is H2PO2-.
3. PO43- (base) -> H3PO4 (conjugate acid)
The formula of the conjugate acid of PO43- is H3PO4.
4. SO32- (base) -> HSO3- (conjugate acid)
The formula of the conjugate acid of SO32- is HSO3-.
To determine the formula of the conjugate acid of a given base, you must add a hydrogen ion (H+) to the base. Here are the conjugate acids of the given bases:
1. HCO3- (Bicarbonate ion): To find the conjugate acid, add a hydrogen ion to the bicarbonate ion. The formula for the conjugate acid is H2CO3 (Carbonic acid).
2. HPO2- (Hypophosphite ion): Adding a hydrogen ion to the hypophosphite ion gives you the conjugate acid, which is H2PO2- (Phosphorous acid).
3. PO43- (Phosphate ion): The conjugate acid of the phosphate ion is obtained by adding a hydrogen ion, resulting in H3PO4 (Phosphoric acid).
4. SO32- (Sulfite ion): By adding a hydrogen ion to the sulfite ion, the conjugate acid is formed, which is H2SO3 (Sulfurous acid).
So, the formulas of the conjugate acids are:
1. Conjugate acid of HCO3-: H2CO3
2. Conjugate acid of HPO2-: H2PO2-
3. Conjugate acid of PO43-: H3PO4
4. Conjugate acid of SO32-: H2SO3
