Barbituric acid, HC4H3N2O3, is used ito prepare various barbiturate drigs (used as sedaives). Without solving the quadratic equation, calculate the concentration of hydrogen ion in a (2.30x10^-1) M solution of the acid. The value of Ka is 9.8x10-5. Express your answer to three significant figures.
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.
