(a)[1]
Why did the student choose a burette rather than a measuring cylinder?
(b)[1]
Why was the student able to stop after $12.0\,\text{cm}^3$ of H rather than taking any more measurements?
(c)[3]
Plot the results from the table on the grid and draw two straight lines that intersect through the points.
(d(i))[1]
Determine the precipitate height when $3.5\,\text{cm}^3$ of H is mixed with $4.0\,\text{cm}^3$ of G.
(d(ii))[1]
Determine the volume of H that must be added to $4.0\,\text{cm}^3$ of G to make a precipitate with a height of $20.0\,\text{mm}$.
(d(iii))[1]
Determine the smallest volume of H that reacts fully with $4.0\,\text{cm}^3$ of G.
(e)[3]
Using your answer to (d)(iii) and the equation, work out the concentration of the potassium iodide in solution G.
