(a)[1]
State why the student chooses a burette rather than a measuring cylinder.
(b)[1]
State the evidence in the table that shows that the reaction is exothermic.
(c)[3]
Plot the table values on the grid and extend both straight lines until they cross.
(d(i))[1]
Find the volume of X that gives a temperature rise of $5.6\,^{\circ}\text{C}$ when it is added to $20.0\,\text{cm}^3$ of W.
(d(ii))[1]
Find the temperature increase when $12.5\,\text{cm}^3$ of X is added to $20.0\,\text{cm}^3$ of W.
(e(i))[1]
Use your graph to find the smallest volume of X that reacts completely with all of the NaOH in $20.0\,\text{cm}^3$ of W.
(e(ii))[3]
Use your answer to (e)(i) together with the equation to find the concentration of $\text{H}_2\text{SO}_4$ in X.
