Practical: Investigate Metals reacting with acids
This practical investigates the reactions between dilute hydrochloric and sulfuric acids and the metals magnesium, iron and zinc. Equal volumes of acid go into three test tubes, a small piece of each metal is added, and any gas given off is tested with a lighted splint. Safety glasses are worn throughout because the acids are being handled directly.
What you know already
From Reactivity Series you know that some metals attack dilute acids to give hydrogen while others barely respond. This note turns that idea into a laboratory method: three metals are dropped into two acids, the gas is tested with a lighted splint, and the speed of each reaction ranks the metals in order.
Key points of understanding
- Five cm3 of dilute acid is measured into each of three test tubes.
- A length of magnesium ribbon, iron filings and zinc turnings go into separate tubes.
- Any gas given off is tested with a lighted splint.
- The whole experiment is repeated using dilute sulfuric acid.
- Safety glasses are put on before any acid is handled.
