What is the full net ionic equation for each reaction? do they form a precipitate or have a color change?
You need to know the solubility of compounds to work these problems. If a ppt (an insoluble material) is produced, then the reaction will proceed. Here is a simplified site that gives the solubility of the most common materials.
Na2S2O3 + AgNO3
hi i was just wondering what the solution would be to:
AgNO3 + Na2S2O3 + sunlight (light enegy)
