A student is carrying out an acid-base titration to determine the concentration of a sodium hydroxide solution. Before pipetting 25.0 cm3 of the sodium hydroxide solution into a conical flask, they rinse the inside of the pipette with distilled water but fail to rinse it with the sodium hydroxide solution.
State the effect, if any, that the water remaining in the pipette will have on the final titre volume of hydrochloric acid needed from the burette.
119 exam-style questions on Edexcel GCSE Chemistry 6.2 Quantitative analysis, covering 6.2.1 Concentration in mol dm⁻³ and titration calculations, 6.2.2 Percentage yield and why actual yield falls short, 6.2.3 Atom economy of a reaction, 6.2.4 Choosing a reaction pathway, and 6.2.5 Molar volume of gases and Avogadro's law. Each one has a worked solution and a mark scheme showing where the marks go.
