Gifblaar is a small South African shrub and one of the most poisonous plants knownbecauseit contains fluoroacetic acid (FCH2COOH), which has a pKaof 2.59. Calculate the initial concentration of fluoroacetic acid in a solution that has the same pH as a 0.00760 M solution of HCl. Nitric acid (HNO3) is a strong acid that is completely ionized in aqueous solutions of concentrations ranging from 1% to 10% (1.50 M ). However, in more concentrated solutions, part of the nitric acid is present as un-ionized molecules of HNO3. For example, in a 50% solution (7.50 M ) at 25°C, only 33% of the molecules of HNO3 dissociate into H+ and NO3–. What is the value of Ka for HNO3? Pyridine (C5H5N) is a particularly foul-smelling substance used in manufacturing pesticides and plastic resins. Calculate the pH of a 0.145 M solution of pyridine (Kb = 1.4×10-9 ). The acetate ion is the conjugate base of acetic acid. The Ka of acetic acid is 1.76×10–5. What is the pH of a 0.400 M solution of sodium acetate? Write a chemical equation for the hydrolysis reaction that explains why an aqueous solution of CH3NH3Cl is acidic.[Please include the states of matter with each chemical species. Remember, it is an equilibrium reaction.]
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.
