Cu(NO3)2(aq)+2NaOH(aq)-->Cu(OH)2(aq)+2NaNO3(s)

Techniques

• First of all we established a practical temperature to heat our solution so the solution didn't boil and our safety was secure.
• While one of us was stirring the solution carefully, making sure it all stayed in the beaker, the other group member was close by making sure that the area around the other group member had no distractions.
• Also we took turns stirring the solution so we had rapid stirring and no tired arms throughout the whole step. We showed very cooperative actions during this step
• We also managed to capture a video while we were accomplishing our task...
