Question

oliver needs to standardize a base solution by titration with an acid solution of known concentration. he finds the volume of the acid solution needed to reach the endpoint for a sample of the base solution. arrange the steps in the order that allows oliver to determine the concentration of the base solution. first step last step answer bank calculate the number of moles of titrant using the volume of titrant required and the concentration of titrant. write a balanced equation for the reaction between the analyte and the titrant. calculate the concentration of the analyte using the number of moles of analyte and the volume of analyte titrated. calculate the number of moles of analyte using the stoichiometric coefficients of the equation.

Explanation:

Step1: Write a balanced equation

First, write a balanced equation for the reaction between the analyte (base) and the titrant (acid). This provides the stoichiometric relationship between them.

Step2: Calculate moles of titrant

Then, calculate the number of moles of titrant using the formula \(n = C\times V\) (where \(n\) is moles, \(C\) is concentration, and \(V\) is volume).

Step3: Calculate moles of analyte

Next, use the stoichiometric coefficients from the balanced equation to calculate the number of moles of analyte.

Step4: Calculate analyte concentration

Finally, calculate the concentration of the analyte using \(C=\frac{n}{V}\) (where \(n\) is moles of analyte and \(V\) is volume of analyte titrated).

Answer:

1. Write a balanced equation for the reaction between the analyte and the titrant.
2. Calculate the number of moles of titrant using the volume of titrant required and the concentration of titrant.
3. Calculate the number of moles of analyte using the stoichiometric coefficients of the equation.
4. Calculate the concentration of the analyte using the number of moles of analyte and the volume of analyte titrated.
