A student needs to standardize a base solution by titration with an acid solution of known concentration. She finds the volume o
f the acid solution needed to reach the endpoint for a sample of the base solution. Arrange the steps in the order that will allow her to determine the concentration of the base solution.
The steps usually involves adding the known solution (the titrant) to a known quantity of the unknown solution (the analyte) until the reaction is complete which can be understood in detail as below with the help of through out process of titration.
<h3 /><h3>What is Titration ?</h3>
A titration is a technique used to work out the concentration of an unknown solution based on its chemical reaction with a solution of knownconcentration.
Steps in order to determine the concenteration of base solution ;
(Acid-Base Titration)
Choose the titrant.
Choose the titrate.
Select the normality of the titrate.
Choose the volume of the liquid to be pipetted out.
Select the indicator.
Start titration.
End point is noted at the colour change of the solution.
From the final reading the normality of titrant can be calculated by the equation:
N₁V₁=N₂V₂
After finding the normality, the amount of given substance in the whole of the given solution can be calculated by the equation:
Mass = Equivalent weight x Normality \ Volume {1000}
Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get
