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.

Explain why the neutralization reaction of a weak acid and a strong base gives a weekly basic solution. A) The reaction of weak acids or bases with strong acids and bases change the Kw of water, leading to a basic solution at equilibrium. B) The excess strong base creates the basic solution. C) The weak acid gets converted to its conjugate base, which then reacts with water. D) The weak acid gets protonated and the protonated weak acid then deprotonates in water. E) This is a trick question – the neutralization of weak acid by base has to yield a neutral solution, not a basic one – that’s why it’s called a neutralization reaction.
