Title: Which reaction is not typical of a dilute acid?
Post by: a123456 on January 21, 2022, 12:30:43 AM

A: Potassium Hydroxide + Sulfuric Acid -> Potassium Sulfate + Water
B: Copper Oxide + Sulfuric Acid -> Copper Sulfate + Water
C: Barium Nitrate + Sulfuric Acid -> Barium Sulfate + Nitric Acid
D: Zinc Carbonate + Sulfuric Acid -> Zinc Sulfate + Carbon Dioxide + Water

The answer provided was C. The only idea I have right now is that dilute acids dissociate partially. However, as seen, all the hydrogen ions of the sulfuric acid dissociate completely in the below reactions.

Thanks for the help.

Did you heard about the law of dilution ? Dilution increases dissociation degree.

Maybe you should consider poor solubility of barium sulfate instead ?
