The Common-Ion Effect

The Common-Ion Effect. Prepared by Prof. Odyssa Natividad R.M. Molo. Consider a solution that contains not only a weak acid (HC 2 H 3 O 2 ) but also a soluble salt (NaC 2 H 3 O 2 ) of that acid. NaC 2 H 3 O 2 (aq) ? Na + (aq) + C 2 H 3 O 2 - (aq)

Balancing Chemical Reactions

Balancing Chemical Reactions. Why?. There are laws!!!!. Matter cannot be created or destroyed only changed. So if you start with 20 hydrogen, you end up with 20 hydrogen. HC 2 H 3 O 2 + NaHCO 3. NaC 2 H 3 O 2 + H 2 O + CO 2. Equations. Vinegar + Baking Soda. Products. Word Equation.
