Water
in solution disassociates into two ions.
What are these two ions? (What caused the charges to happen?)
Because water does this it is considered a universal……… Solvent. (Keep in mind though... while it is called this, water CANNOT dissolve EVERYTHING - For instance any it cannot dissolve any Nonpolar substances!!)
Write the equation and diagram out How salt (NaCl) dissolves in water
 |
The positive Sodium (Na) will be attracted to the Negative Hydroxide ion (OH) to form NaOH (Sodium Hydroxide), while the Negative Cloride (Cl) will be attracted to the Positive Hydrogen ion to form HCl (Hydrochlorid acid) in what would be known as a double displacement reaction. |
In reality this is usually what happens!!!
 |
| The water molecules remain in their bonded form but different areas of the water molecules are drawn to either Na+ or Cl-
I then gave you the general guidelines of your water lab wrap up:
and I had Hank Green from Crash Course give you a final review on all of this!!
You started your lab write up, I asked for you to finish it tonight. If there are still questions tomorrow about it, I will answer them and this will be due by the end of the period tomorrow!!
