What is the conjugate acid of O2^-2

?

The conjugate acid of O2^-2 is O2.

To determine the conjugate acid of O2^-2, we need to consider the acid-base reaction involving O2^-2.

The O2^-2 ion is a strong base, known as oxide ion. When a base accepts a proton (H+), it forms its conjugate acid. Therefore, the conjugate acid of O2^-2 is formed when O2^-2 accepts a proton (H+).

O2^-2 + H+ -> H2O (water)

H2O is the conjugate acid of O2^-2.

To determine the conjugate acid of O2^-2, we need to understand the concept of conjugate acids and bases.

An acid donates a proton (H+) and its conjugate base is the species that remains after the proton is donated. In this case, O2^-2 is a negatively charged species, indicating that it has gained two extra electrons.

To find the conjugate acid, we need to determine the species that would result from the addition of a proton to O2^-2. Since O2^-2 has a charge of -2, adding a proton (H+) would neutralize this charge. Therefore, the conjugate acid of O2^-2 would be H2O (water).

The equation representing the reaction between O2^-2 (peroxide ion) and H+ (proton) to form water (H2O) as the conjugate acid is:

O2^-2 + H+ -> H2O
