Question

a certain indicator has a color chart that shows that when the indicator is yellow, the solution is acidic. what is true about a solution that produces a yellow indicator? the solution has more hydronium ions than hydroxide ions. the solution contains neither hydroxide ions nor hydronium ions. the solution contains nothing but water. the solution has a ph greater than 7.

Explanation:

Acidic solutions have a higher concentration of hydronium ions ($H_3O^+$) than hydroxide ions ($OH^-$). A pH greater than 7 indicates a basic solution. Pure water is neutral and has equal amounts of hydronium and hydroxide ions. Since the indicator shows the solution is acidic, it must have more hydronium ions than hydroxide ions.

Answer:

The solution has more hydronium ions than hydroxide ions.
