Reaction between metals and acids – Lead and other metals which are more reactive than lead in the reactivity series can react with hydrochloric acid and sulphuric acid and form salts. Q. Hydrogen is not a metal but it has been assigned a place in the reactivity series of metals. So, by reactivity series you can tell which metal will displace another metal. It is also known as activity series. The arrangement of metals in a vertical column in the order of decreasing reactivities is called reactivity series of metals. Thus the most reactive metal is placed at the top of the series while the least reactive metal is placed at the bottom of the series. Gold has very low reactivity and therefore can be found in its metallic state in nature. Reading Time: 1min read 0. Model 1. Materials Metals and Non-Metals ... reactivity series of metals is a series in which metals are arranged in decreasing order from the most reactive metal to the least reactive metal. When we move down the series the electron-donating capacity of metals decreases. Three different worksheets: The first is an observation sheet, where students write in what they saw happen when metals react with acid, water and oxygen. Sodium and Potassium are highly reactive metals. This material is for class teaching / revision or individual study. Displacement reaction does not occur because copper metal is less reactive than iron metal.So a less reactive metal copper cannot displace a more reactive metal iron from its salt solution,iron sulphate solution.
