Question 9 Which of the following statements is false? The strengths of binary acids increase from left to right within the same period. For a given central atom, the acid strength of an oxoacid increases as the number of oxygens on the central atom increases. The strengths of binary acids decrease from top to bottom within the same group. When the central atoms of oxoacids holds the same number of oxygen atoms, the acid strength increases from bottom to top within a group. When the central atoms of oxoacids holds the same number of oxygen atoms, the acid strength increases from left to right within a period.

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.
