Consider the following acids: H2S, HPO4.
Write the formula of the conjugate base for H2S.
Express your answer as an ion.
The formula of the conjugate base for H2S is HS- (hydrogen sulfide ion).
The formula of the conjugate base for H2S can be determined by removing one hydrogen ion (H+) from H2S.
H2S is a weak acid that can donate one hydrogen ion, so removing one hydrogen ion would result in the formation of the sulfide ion (S^2-).
Therefore, the formula of the conjugate base for H2S is S^2-.
To determine the formula of the conjugate base for H2S, first, let's understand what a conjugate base is. A conjugate base is a species that is formed when an acid donates a proton (H+) during a dissociation reaction.
In this case, the acid is H2S (hydrogen sulfide). To find the conjugate base, we remove one proton (H+) from the acid. H2S has two hydrogen ions (H+), so removing one proton results in the formula HS- (hydrogen sulfide ion).
Therefore, the formula of the conjugate base for H2S is HS-.
