When samples ca(oh)2 is titrated with HCL, then the concentration of ca(oh)2 is calculated as 0.09M.
<h3>What is neutralization reaction?</h3>
In chemistry, neutralization is a chemical reaction in which acid and base react with each other. During reaction in water, neutralization results in no excess of hydrogen or hydroxide ions present in the solution.
The neutralization of acid and base to identify the strength can be given as:
M1V1= M2V2
Substituting the strength and the volume of calcium hydroxide and the HCl with the volume:
0.030 * 38.1 = M2 * 25
M2 = 1.143/25
=0.045 M
The strength of the calcium hydroxide in the reaction is 0.045 M.
One molar unit of calcium hydroxide gives 2 molar units of hydroxide;
Therefore, molar unit of hydroxide in 0.045 M calcium hydroxide is:
2 * 0.045 = 0.09 M
The concentration of hydroxide ion in the titration is 0.09M.
