A student compares 25.0 cm3\mathrm{cm^{3}}cm3 of 0.10 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3 ethanoic acid with 25.0 cm3\mathrm{cm^{3}}cm3 of 0.10 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3 hydrochloric acid. Excess magnesium ribbon is added to each acid.
Statement 1: the ethanoic acid has a higher pH because it is only partially ionised in water
Statement 2: both acids eventually produce the same total volume of hydrogen
Statement 3: the ethanoic acid reacts more slowly because it is a more dilute acid
Which statements are correct?
1 only
1 and 2 only
1 and 3 only
2 and 3 only
