15. Methylamine is a weak base with the formula, CH3NH2, the Kb for methylamine is 4.38 x 10-4 In aqueous solution, methylamine partially dissociates according to the following reaction: CH3NH2 + H2O ⇔ CH3NH3+ + OH- Use the Kb equation to calculate the pH of the aqueous methylamine solution described below: Volume: 375 mL Concentration: 0.2570 M Since this is a weak base, you can assume the amount of base dissociated is << 5% of the total amount of base present. Report your answer with the correct number of significant digits.
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.
