we are looking at the way compounds are put together. The way we view the formation is through Chemical Reactions and we have some basic concepts that would be useful to know:
How to know when a reaction occurs:
* Bubbles (gas formation)
* Heat (lost or gain)
* Precipitations (solid formation)
* Light
* electron flow (batteries?)
In today’s lab you will be looking at a type of reaction called “Double Displacement”. Please use your lab manual and go to Experiment 3. do the Postlab questions in the manual
1.BaCl2 + Na2SO4 Reaction Between Sodium Sulphate and Barium Chloride Solution – MeitY OLabs
2.Precipitation experiment: Precipitation Reaction Experiment
Solution #1: Ag(NO)3 + Cu(NO3)2
Solution #2: Ag(NO)3 + Na2S
Solution #3: Ag(NO)3 + NaCl
Solution #4: Ag(NO)3 + Na2S
Solution #5: Cu(NO3)2 + NaCl
Solution #6:NaCl+ Na2S
