Assessment: WAEC SSCE - Chemistry - 2001 (Objective) Subject: Chemistry

Question 1 Report

Which of the following pairs of reagents reat to produce hydrogen?
Answer Details
The pair of reagents that react to produce hydrogen is: Magnesium and dilute tetraoxosulphate (VI) acid. When magnesium is added to dilute tetraoxosulphate (VI) acid, hydrogen gas is produced as one of the products. This is a classic example of a single-displacement reaction, where the more reactive metal (magnesium) displaces the less reactive hydrogen from the acid. The other options do not produce hydrogen gas upon reaction.
