(a)[1]
Name the apparatus A.
(b)[1]
The student adds $25\text{ cm}^3$ of dilute sulfuric acid to apparatus A. Name a suitable piece of apparatus for measuring the $25\text{ cm}^3$ of acid.
(c)[1]
The student heats the mixture in apparatus A until it reaches $60\,^{\circ}\text{C}$. Name a suitable piece of apparatus to measure the temperature.
(d(ii))[2]
Plot the results within the grid.
(d(iii))[1]
Draw a best-fit curve.
(d(iv))[4]
Use the graph to work out the time at $25\,^{\circ}\text{C}$, extend your curve of best fit to find the temperature for a $180\text{ s}$ reaction, and suggest why an experiment at $70\,^{\circ}\text{C}$ is not carried out.
