A student carries out an investigation on two acids W and X. Equal volumes of W and X are reacted separately with excess magnesium. The student records these observations. 1 Hydrogen gas is produced more quickly with W than with X. 2 The final volume of hydrogen gas produced is the same for both acids. Which statement accounts for these observations?
- AThe pH of W is higher than the pH of X.
- BW is an organic acid.
- CW is a stronger acid than X.
- DW is more concentrated than X.
