Describe the term molarity as it relates to an acid or base.

Molarity, also known as concentration in amount of matter, is the ratio between the amount of solute matter, measured in mol (n1), and the volume of solution in liters (V). This concentration is measured in mol per liter (mol / L). It is often called by some authors molar concentration, but the correct terms are "concentration in mol / L" or "concentration in amount of matter".

Consider the gastric juice that our stomach produces for the purpose of performing the digestion process. In fact, it is a hydrochloric acid (HCl) solution at a concentration of 0.01 mol / L. This means that for every liter of gastric juice there is 0.01 mol HCl. The same goes for basic concentration solutions. Consider a NaOH solution at a concentration of 0.02 mol NaOh. This means that if each NaOh litter is present, there is 0.02 mol of NaOh.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
