The concentration of the HCl solution is 0.74 M
Titration is a not unusual laboratory technique of quantitative chemical analysis to decide the attention of an identified analyte. A reagent, termed the titrant or titrator, is ready as a widespread solution of acknowledged awareness and quantity.
Titration is the gradual addition of one answer of recognized attention to a regarded extent of every other answer of unknown awareness till the reaction reaches neutralization, that's often indicated by using a shade alternate.
The purpose of the titration is the detection of the equivalence factor, the point at which chemically equivalent quantities of the reactants were mixed. the quantity of reactants that have been mixed on the equivalence factor depends on the stoichiometry of the reaction.
calculation:-
N₁ = 0.300 M
V₁ = 50.00 ml
N₂ = ?
V₂ = 20.25 ml
N₁V₁ = N₂V₂
N₂ = N₁V₁ / V₂
= 0.3 × 0.05 / 0.02025
= 0.74 M
