Name one piece of apparatus that can measure $25.0\,\text{cm}^3$ accurately.
Name apparatus A.
Why is it incorrect to rinse the burette with distilled water just before filling it with M?
At the end-point, what colour change does methyl orange show? The colour changes from [BLANK] to [BLANK].
Use the diagrams to fill in the table. Tick the best titration results and then use them to calculate the average volume of M.
M is $0.0500\,\text{mol dm}^{-3}$ sulfuric acid, $\text{H}_2\text{SO}_4$. Determine the number of moles of $\text{H}_2\text{SO}_4$ in the average volume of M used during the titration.
Dilute sulfuric acid reacts with aqueous sodium hydroxide as shown. $\text{H}_2\text{SO}_4 + 2\text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O}$ Find the number of moles of NaOH in $25.0\,\text{cm}^3$ of L.
Find the number of moles of NaOH present in $500\,\text{cm}^3$ of L.
Find the number of moles of NaOH present in $25.0\,\text{cm}^3$ of K.
Find the concentration of NaOH in K, and give the answer to three significant figures.
State and explain whether the second student's titration volume of dilute sulfuric acid would be smaller, larger, or unchanged compared with the first student's volume.
