If you have two barrels and one contains silver nitrate and the other contains sodium nitrate. How would you?
If you have two barrels and one contains silver nitrate and the other contains sodium nitrate.
How would you figure out which barrel contains what using only items that are normally found in the kitchen of a home?
Take a small sample from each barrel in turn and dissolve in water. Add salt solution to each of the sample solutions.
The silver nitrate solution will form a white precipitate of insoluble silver chloride.
The sodium nitrate solution will appear unchanged, since the products of the reaction are both soluble.
