Wednesday, November 4th
Take out your single replacement practice, purple homework sheet, and any other homework that needs to be checked off
Complete the following in your notebook:Kidney stones are solid blockages that sometimes
occur in the kidney. Calcium chloride and sodium oxalate react in a double replacement reaction in the body to form one type of kidney stone. Based on the reactants, predict the products and predict which compound is most likely the kidney stone. Write a complete balanced equation.
CaCl2 (aq) + Na2C2O4 (aq) → ____ + ____

Solubility Rules
Some ionic compounds don’t actually dissolve in water
We use solubility rules to remind of us which ones do and don’t
You do not have to memorize theseTape it into your notebook!
