for the original proposal you will need two titrant concentrations. you will be given a 0.5 m stock solution which you will use for the first titrant. the second titrant will be created by diluting the 0.5 m stock solution to 0.1 m. what volume of the stock solution will you need to prepare 25 ml of the 0.1 m titrant solution?



Answer :

5ml of stock solution would need to prepare a 25ml of 0.1 molar of titrant.

A stock solution is a standardized solution where we a aware of both the concentration and volume of the solution. To prepare a stock solution, we need required amount of distilled water and the molar concentration of the solution we are preparing.

      In a stock solution, we need to dilute the concentration by adding water to the solution. In the given question we have 0.5 molar stock solution that is needed for the titrant. Here, we r given three titrants, one with 0.5m stock solution, second with dilution of 0.5m solution to 0.1molar. In the third we need 5 ml of stock solution to prepare a 0.1m titrant.

    Titration is a quantitative method of determining the concentration of a given sample.
