Post lab questions
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
