Answer :
When a 25.0-ml sample of HCl is titrated with 0.350 m KOH. 34.6 ml of the base are required to reach the equivalence point. The concentration of HCl is 0.4844 M
The concentration of a substance is the amount of solute contained in a given volume of solution. Concentration is usually expressed in terms of molarity, expressed as the number of moles of solute in 1 L of solution. Solution concentration is the degree to which a solute is dissolved in a given amount of solvent or solution. An enriched response is a response that contains a very large amount of solute.
Concentration of HCl can be calculate as follows:
Titration is the process of determining the amount of substance A by adding measured increments of substance B, the titrant with which it reacts, until exact chemical equivalence is reached (equivalence point).
The formula (Macid x V acid =Mbase x Vbase ) represents the titration formula in chemistry.
M acid x V acid =Mbase x Vbase
Macid =Mbase x Vbase
V acid
Macid = 0.350 M x 34.6mL
25mL
M HCl = 0.4844 M
Therefore, when a 25.0-ml sample of HCl is titrated with 0.350 m KOH. 34.6 ml of the base are required to reach the equivalence point. The concentration of HCl is 0.4844 M
