Chem 105 Online Safety: While these are household items that you could easily purchase at the store, please understand that this is still for chemistry purposes. Do not INGEST anything or leave readily available for pets and young children to get into (especially your chalk, um-I mean your final precipitate). All items can be thrown away at the end. Ice melt solutions can be thrown away outside away from pet areas. Even though Calcium Carbonate is relatively harmless-please note that this should not be ingested. Prelab: 1. If you had to make a 0.750M solution of Na2CO3 from 100mL of solution, determine the mass of Sodium Carbonate necessary. 100mL 1000 ML/LX. 750 mol/L = .075 mol mass of Na₂CO3 = 106g/molx.075md=7.95g Na₂CO3-1069/mol 2. If you had to make a 0.250M solution of CaCl2 from 100mL of solution, determine the mass of Calcium Chloride necessary. 250m 1000 me X100ML = F.025ML of 3. If you use 10.0 mL of the Sodium Carbonate solution and an excess of Calcium Chloride, how many grams of Calcium Carbonate should be theoretically be produced? 10.0mL grams Na203 +CaCl2 +CaCO3+ 2NaCl .750M 4. If you use 25.0 mL of the Calcium Chloride solution and an excess of Sodium Carbonate, how many grams of Calcium Carbonate should be theoretically be produced?

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
