Take two 250 mL beakers from the Containers shelf and place them on the workbench.
Add 150 mL of 1 M sodium hydroxide (NaOH) solution from the Materials shelf to one of the beakers.
Add 60 mL of 1 M nickel(II) chloride solution (NiCl2) from the Materials shelf to the other, empty, beaker. You may want to label your beakers by double-clicking on each and entering a name.
Observe the contents of each beaker. Record the observations.
Pour the entire contents of one beaker into the other. Record your observations of the reaction that occurs. You may wish to zoom in to examine the beaker more closely.
What is the complete, balanced equation for the double displacement reaction carried out in Experiment 4. (Hint: The solid is a compound of Ni2+ ions and hydroxide ions.) Write the complete molecular equation rather than the net ionic equation.
