Will R react with dilute hydrochloric acid? Will R displace copper from copper sulphate solution? (7) 7) (i) Explain why the reactivity of metal is increasing down a group. (ii) Explain why Sodium is more reactive than Magnesium and Aluminium. (4) Title Author
Corrosion data for a various stainless steels in an extensive range of media. The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables
Any metal that reacts quickly with water is likely to react dangerously violently with acids. Most of them would explode on contact with even dilute Hydrochloric acid. Aluminium is a little less reactive, and takes a while to start reacting because it is covered with a layer of Aluminium Oxide that protects the pure metal from the acid briefly.

Magnesium rapidly dissolves in dilute sulphuric acid to give a clear colourless solution. Calcium only reacts slowly with dilute sulphuric acid to give a cloudy solution. Magnesium oxide and magnesium carbonate are similar white powders which are slightly soluble in
If dilute sulphuric acid (H 2 SO 4 ) is used instead of dilute hydrochloric acid (HCl ) for reaction with the metals. Predict what you will observe and the products formed if any
(d) When a metal reacts with dilute hydrochloric acid, it forms metal chloride and hydrogen gas. Example: Magnesium reacts rapidly with dilute hydrochloric acid to form magnesium chloride and hydrogen. Lakhmir Singh Chemistry Class 10 Solutions Page No
Metal C is still less reactive because it can displace only silver from its salt solution and metal D is the least reactive because it cannot displace any metal from its salt solution. Hence, the decreasing order of reactivity of the metals is B > A > C > D. Question 4.
Metal: Reaction with hydrochloric acid: Order of reactivity: Products: Magnesium Vigorously reacts with a stream of gas evolving. 1 st - most reactive. Magnesium chloride, MgCl 2 and hydrogen gas. Zinc Quite slow reaction with a steady stream of gas evolving. 2 nd.
When dilute hydrochloric acid, HCl(aq), is added to sodium thiosulfate, Na 2S 2O3(aq), in a conical flask, the following reaction occurs The beakers show particle representations of magnesium metal and hydrochloric acid just before the reaction is about to 2
metal + dilute acid → salt + hydrogen 1. The reaction of potassium and sodium with a dilute acid is explosive. 2. Other metals like calcium, magnesium, zinc and iron will produce their corresponding salts, liberating the colourless and odourless gas hydrogen.

The Reactivity Series The Reactivity Series shows the order of reactivity of metals in their reactions with water, steam, and dilute acids. Potassium (K) Sodium (Na) Calcium (Ca) Magnesium (Mg) Aluminium (Al) Zinc (Zn) Iron (Fe) Lead (Pb) Copper (Cu) Silver (Ag) Most reactiveMost reactive Least reactiveLeast reactive Metals and Their Reactivity Chapter 19
Calcium and the metals that are more reactive than calcium in the reactivity series can react with cold water to form the corresponding hydroxide while liberating hydrogen gas. For example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below.
