How do I calculate the concentration of KOH in solution B from titration data?

Question

ScanSolve AI Tutor · Accepted Answer

To determine the concentration of KOH in solution B in $\text{mol dm}^{-3}$ , I need more information from your results and the information provided in the experiment.

Specifically, I need:

The volume of KOH solution (B) used in the titration (usually the titre value).
The concentration of the acid (e.g., $\text{CH}_3\text{COOH}$ ) used to titrate the KOH.
The volume of the acid used (if it was the analyte) or the volume of KOH (if it was the analyte) that reacted completely.
The balanced chemical equation for the reaction between KOH and the acid.

Once this information is available, the concentration can be calculated using the following steps:

Write the balanced chemical equation for the reaction.
For example, if the acid is $\text{CH}_3\text{COOH}$ :
$\text{CH}_3\text{COOH(aq)} + \text{KOH(aq)} \longrightarrow \text{CH}_3\text{COOK(aq)} + \text{H}_2\text{O(l)}$
From this, determine the mole ratio between $\text{CH}_3\text{COOH}$ and $\text{KOH}$ . In this case, it is $1:1$ .
Calculate the moles of the known reactant (e.g., $\text{CH}_3\text{COOH}$ ) using its concentration and volume.
$\text{Moles} = \text{Concentration} \times \text{Volume (in dm}^3\text{)}$
Use the mole ratio from the balanced equation to find the moles of KOH that reacted.
Calculate the concentration of KOH using the moles of KOH and the volume of KOH solution B used in the titration.
$\text{Concentration of KOH} = \frac{\text{Moles of KOH}}{\text{Volume of KOH (in dm}^3\text{)}}$
