Question 9

A student is performing a titration to analyze a solution of sodium hydroxide ( $NaOH\text{NaOH}$ ).

The student measures $cm325.0\text{ cm}^3$ of sodium hydroxide solution with a concentration of $g/dm34.80\text{ g/dm}^3$ . Calculate the mass of sodium hydroxide in this sample. Use the conversion: $cm31\text{ dm}^3 = 1000\text{ cm}^3$ .

[3]

During the titration, the following volumes of dilute sulfuric acid were recorded to neutralize the sodium hydroxide:

Trial 1: $cm324.1\text{ cm}^3$
Trial 2: $cm320.3\text{ cm}^3$
Trial 3: $cm324.3\text{ cm}^3$
Trial 4: $cm324.2\text{ cm}^3$

Identify the anomalous trial and calculate the mean volume of acid used, using only the concordant results.
