Explain why a pipette is selected rather than a measuring cylinder for measuring $25.0\,\text{cm}^3$ of solution K.
Name the vessel used to prepare solution L.
Identify the liquid used to rinse the pipette.
Explain why the conical flask is stood on a white tile.
State the colour change shown by the methyl orange indicator at the end-point.
Use the diagrams to fill in the table and work out the average volume of $\text{H}_2\text{SO}_4(aq)$ added.
Calculate the amount of substance of $\text{H}_2\text{SO}_4$ present in the average volume of $0.100\,\text{mol dm}^{-3}$ $\text{H}_2\text{SO}_4(aq)$.
Use $2\text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O}$ to find the number of moles of $\text{NaOH}$ in $20.0\,\text{cm}^3$ of solution L.
Calculate the number of moles of $\text{NaOH}$ present in $250\,\text{cm}^3$ of solution L.
Deduce how many moles of $\text{NaOH}$ are in $25.0\,\text{cm}^3$ of solution K.
Calculate the concentration of solution K in $\text{mol dm}^{-3}$.
State whether the average titration volume of $\text{H}_2\text{SO}_4(aq)$ becomes smaller, larger, or unchanged when 20 drops of methyl orange are used, and explain your answer.
