State the reaction type for the process that occurs between $\text{HCl\,(aq)}$ and $\text{NaOH\,(aq)}$.
Name an item of apparatus that could make the volume of $\text{NaOH\,(aq)}$ added to the beaker more accurate.
Name the apparatus used to add the $4.0\ \text{cm}^3$ portions of $\text{HCl\,(aq)}$.
Explain why a glass beaker is not the best apparatus for this experiment. Suggest an improvement.
Plot temperature against the total volume of $\text{HCl\,(aq)}$ on the grid.
Mark the anomalous point with a circle on the grid.
Draw a straight best-fit line through the points from $0$ to $16\ \text{cm}^3$.
Draw a straight best-fit line through the points from $20$ to $32\ \text{cm}^3$. Extend both lines until they meet.
Use the intersection to find the minimum volume of $\text{HCl\,(aq)}$ required to react with all of the $\text{NaOH\,(aq)}$.
Use the intersection to work out the temperature change, $\Delta T$, caused by the reaction.
The heat change for this reaction is found from: heat change $=$ mass of solution $\times$ specific heat capacity $\times$ temperature change. $1.0\ \text{cm}^3$ of this solution has a mass of $1.0\ \text{g}$. State the value used for the mass of solution.
The actual heat change for this reaction is much larger than the calculated value. Suggest one reason for this difference.
