Making predictions using the reactivity series
4 marks · NormalTitanium is a metal that lies between aluminum and zinc in the reactivity series.
Predict whether titanium will react with dilute sulfuric acid at room temperature. Give a reason for your answer.
Suggest what would happen if titanium powder is heated with steam. Name a product that would be formed.
Work this out on paper, then compare with the answer and worked solution below. With a free account you can submit written answers for marking.
Show answer
(a) Yes; titanium is above hydrogen in the reactivity series so it will react with dilute sulfuric acid to produce hydrogen.
(b) Titanium will react with steam to form titanium(IV) oxide and hydrogen gas. · must show Reaction occurs, At least one correct product: titanium(IV) oxide or hydrogen
Common mistakes: Assuming titanium reacts with acids rapidly; Incorrect products with steam

Marking points
B1 (a) · 1 mark · Predicts titanium will react with dilute sulfuric acid.
B2 (a) · 1 mark · Gives reason: titanium is above hydrogen in the series or can displace hydrogen.
B3 (b) · 1 mark · States titanium reacts with steam.
B4 (b) · 1 mark · Names a correct product (titanium(IV) oxide or hydrogen gas).
Worked solution
a) Titanium will react with dilute sulfuric acid because it is above hydrogen in the reactivity series.
b) On heating with steam, titanium reacts to form titanium(IV) oxide and hydrogen gas.
