Question

Give the conjugate base of the following Bronsted-Lowry acids:

a. HIO₃
b. NH₄⁺
c. HCOOH
d. HPO₄⁻

Answer 1

The conjugate bases of HIO3, NH4+, HCOOH, and HPO4- are IO3-, NH3, HCOO-, and PO43-, respectively. Each conjugate base is formed by removing one proton from the corresponding Bronsted-Lowry acid.

Step-by-step explanation:

To give the conjugate base for each Bronsted-Lowry acid provided, we need to determine what each species becomes after donating a proton (H+). Here they are:

• a. HIO3 - The conjugate base is IO3− (iodate ion).
• b. NH4+ - The conjugate base is NH3 (ammonia).
• c. HCOOH - The conjugate base is HCOO− (format ion).
• d. HPO4− - The conjugate base is PO43− (phosphate ion).

Remember that the conjugate base is formed by removing a proton from the Bronsted-Lowry acid, leading to a decrease in the hydrogen atom count by one and an increase in the negative charge by one unit.
