The quicker the limewater becomes milky, the greater the rate of decomposition of the carbonate (meaning the carbonate is less stable). Reactivity series of metals Royal Society Of Chemistry 56K views 1 year ago Reactivity Series song TheGNThree 608K views 10 years ago Trends in the Periodic Table Reactivity Stile. Which of the following is MOST reactive answer choices Magnesium Lead Tin Copper Zinc Question 2 120 seconds Q. The stability of the metal carbonates can be measured by heating the carbonate and bubbling the carbon dioxide given off through limewater. The higher up the series a metal is, the more reactive the metal is and so the more stable the metal carbonate is.
The stability of the metal carbonates can be related to the reactivity series of metals. This is the 1st lesson from the GCSE C5: Chemical changes topic. However, copper is a very unreactive metal, which is why it is useful for making water pipes, and so copper(II) carbonate is quite unstable and decomposes at a relatively low temperature. During this distance learning lesson (the reactivity series) GCSE / High School students work through the digital worksheet activities to develop their understanding of the order of reactivity of metals based on experimental results. Understanding the reactivity series is fundamental to chemistry. This means that sodium carbonate is very stable and requires a high temperature to decompose. The reactivity series lists elements (mostly metals) in order of decreasing reactivity. If we take the two examples above, sodium is a very reactive metal. The difficulty of this decomposition reaction depends on the reactivity of the metal in the metal carbonate. A more reactive metal will displace a less reactive metal from solution.

Sodium carbonate → sodium oxide + carbon dioxideĬopper(II) carbonate → copper(II) oxide + carbon dioxide Watch this video to show you how to work out the reactivity Series of the metals. GCSE CHEMISTRY - Revision Questions - The Reactivity Series of Metals - Reaction of Metals with Air, Water and Dilute Acid - Metal Displacement Reactions - Oxidation and Reduction - GCSE SCIENCE. When metal carbonates are heated, they break down to form the metal oxide and carbon dioxide gas. to make half equations:īy writing our equation in this way, we can immediately see that copper had to gain two electrons ( reduced) in this reaction, and those electrons came from magnesium ( oxidised).One common reaction of any metal carbonates is known as thermal decomposition. These look at how the electrons behave. We can see there are only two different chemicals involved, and we can split our equation in half. Once we have an ionic equation, we can take it one step further and look at half equations.

Group 7 elements need to gain 1 electron to have a full shell.
For stability, the atom needs to have a full outer shell. These are of no interest in the reaction, so we can ignore them and write out our ionic equation: As we descend Group 7, the reactivity decreases. We can identify the ions that don't change, these are called the spectator ions. Then we can write out all the ions involved:Ĭu²⁺(aq) + SO 4²⁻(aq) + Mg(s) → Cu(s) + Mg²⁺(aq) + SO 4²⁻(aq) This is useful as it shows what is oxidised and reduced. We can start by writing a balanced symbol equation for a reaction: Metals and reactivity series - (CCEA) Redox, rusting and iron - (CCEA). Ionic equations only show us the ions that change in a chemical reaction. This is very costly, in terms of both money and energy. Metals more reactive than carbon have to be extracted using electrolysis. As the carbon is more reactive, it will displace the metal in its ore - reducing the metal.
Metals less reactive than carbon can be extracted by heating the metal with carbon. Metals less reactive than hydrogen are generally found in their elemental form in the Earth's crust ( native state). The non-metals hydrogen and carbon are often included in the reactivity series to give an indication about how the metals can be extracted. The metals potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper can be put in order of their reactivity from their reactions with water and dilute acids. Metals can be arranged in order of their reactivity in a reactivity series. The reactivity of a metal is related to its tendency (how likely it is) to form positive ions. When metals react with other substances the metal atoms form positive ions.
