2. A water sample from a local cave system was tested for total water hardness. An EDTA titer was prepared by titrating 30.00 mL aliquot from 1750.00 pm CaCO: standard. For the standardization, it took 50.10 mL EDTA. A 30.00 mL water sample aliquot was then tested for total hardness, and it used 44.30 mL EDTA. Summary of results: Standardization 1750 ppm Volume of sample EDTA (mL) used Sample analysis 30.00 mL CACO3 standard Standard aliquot EDTA (mL) used Determine the following: a. Titer (mg CaCO3/mL EDTA) b. Total hardness (ppm CaCO3) 30.00 mL 44.30 mL 50.10 mL
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.
