Sodium Benzoate (PhCOONa) is commonly used as a food preservative. It is generally thought to be harmless at low doses, but at high doses there is evidence of harm to liver and/or kidneys and it has been linked to causing or exacerbating ADHD symptoms in children. 1. Draw the chemical equilibrium involving the acid- base reaction between carbonic acid (H₂CO3) and sodium benzoate (PhCOONa). Include the entire bond-line structures for all species. 2. Draw curved arrows to show the mechanism of formation of product from reactants. 3. Look up the pka's of carbonic acid and Benzoic Acid. Is this reaction favored toward products or reactants? Explain.

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.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
