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

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
