Edexcel IGCSE Chemistry 2.15 metal reactions with water and acid
Edexcel IGCSE Chemistry syllabusChemistry 4CH1First assessment 2019

Practise metal-reactivity questions by using water or acid reaction evidence and observations to place unknown metals in the series.

How this is tested

  • Order metals from reaction evidence with water or dilute hydrochloric or sulfuric acid.
  • Choose which unknown metal could be magnesium or copper from its reactivity position.

Question 6

[Maximum number: 3]

The reactions of metals with water and with dilute sulfuric acid can be used to determine the order of reactivity of the metals.

The table shows the reactions of four metals, W, X, Y and Z, with water and with dilute sulfuric acid.
