10 ml of HCl was required to reach the equivalence point
What do you understand by the law of equivalence?
The equivalents of one material will always be equal to the equivalents of the other when two substances react, and the equivalents of any product will always be equal to that of the reactant.
By applying equivalence law:-
M1V1=M2V2
NaOH=HCl
1.0 x 10.0 = 1.0 x V4
V4 =[tex]\frac{1.0 * 10.0}{1.0}[/tex]
V4=10 ml
10 ml of HCl was required to reach the equivalence point.
What is the equivalence point?
The point at which chemically equivalent amounts of reactants have been combined is known as the equivalence point, also known as the stoichiometric point, in a chemical process. The equivalence point for an acid-base reaction is the point at which, in accordance with the chemical reaction, equal amounts of acid and base would neutralize one another. Simply that the ratio is the same as in the chemical reaction is all that is implied, not necessarily a 1:1 molar ratio of acid to base. It can be located using an indicator, such as methyl orange or phenolphthalein.
