Fill in the missing chemical formulae in the tables below.acid conjugate base base conjugate acidHCO−3 H2PO−4 HCl I− H2O SO2−4

To fill in the missing chemical formulae, we will denote the following:

1. Acids are proton donors, and their conjugate bases are formed by losing a proton (H⁺).
2. Bases are proton acceptors, and their conjugate acids are formed by gaining a proton (H⁺).

Step 1: Identify the missing conjugate base for HCO₃⁻

• HCO₃⁻ (bicarbonate) can lose a proton to form its conjugate base.
• Thus, HCO₃⁻ → H⁺ + CO₃²⁻.
• The conjugate base of HCO₃⁻ is CO₃²⁻.

Step 2: Identify the missing conjugate acid for H₂PO₄⁻

• H₂PO₄⁻ (dihydrogen phosphate) can accept a proton to form its conjugate acid.
• Thus, H₂PO₄⁻ + H⁺ → H₃PO₄.
• The conjugate acid is H₃PO₄.

Step 3: Identify the missing conjugate base for HCl

• HCl (hydrochloric acid) can lose a proton to form its conjugate base.
• Thus, HCl → H⁺ + Cl⁻.
• The conjugate base is Cl⁻ (not I⁻).

Step 4: Identify the missing conjugate acid for H₂O

• H₂O (water) can accept a proton to form its conjugate acid.
• Thus, H₂O + H⁺ → H₃O⁺.
• The conjugate acid is H₃O⁺.

Step 5: Identify the missing conjugate base for SO₄²⁻

• SO₄²⁻ (sulfate) can lose a proton to form its conjugate base.
• Thus, SO₄²⁻ → H⁺ + HSO₄⁻.
• The conjugate base is HSO₄⁻.
