Question

Potassium chromate (K2CrO4) is sometimes used with other compounds to check for the presence of silver. Which of these formulas is correct for a silver-containing precipitate in such a reaction?
Answered by GPT-4o mini
When potassium chromate (K2CrO4) is used to test for the presence of silver ions (Ag+), it can react to form a silver chromate precipitate. The correct formula for the silver-containing precipitate formed in this reaction is silver chromate, which is represented by the formula Ag2CrO4.

Thus, the correct formula for the silver-containing precipitate is **Ag2CrO4**.
