Concept explainers

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.

MATLAB The acidity of solutions is generally measured in terms of pH. The pH of a solution is defined as theconcentration of hydronium ions. Create a table of conversions from concentration of hydronium ionto pH, spaced logarithmically from 0.001 to 0.1 mol/liter with 10 values. Assuming that you havenamed the concentration of hydronium ions H_conc, the syntax for calculating the negative of thelogarithm of the concentration (and thus the pH) is:pH = -log10 (H_conc)
