i d k but from using grammar, i'd go with C because you dont say "a" then put a vowel as the start of the next word, cos it would be an instead
The compounds in the reaction that shifts the equilibrium with the common ion effect are
.
<h3>What is the common ion effect?</h3>
The equilibrium condition has an equal amount of reactant and products in the reaction.
The addition of ions same as product or reactant results in a change in the equilibrium of condition and shifts the equilibrium in opposite direction.
The given reaction is:

The addition of sulfate and hydrogen ions shifts the equilibrium.
Thus, the compounds that shift the equilibrium for the reaction are
