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.

In an experiment to find the percentage of calcium carbonate in sand from a beach, 1.86 g of sand reacted with an excess of dilute hydrochloric acid to give 0.55 g of carbon dioxide. CaCO3 (s) + 2HCL (aq) – CaCl2(aq) + CO2(g) + H2O (l) 1.Calculate the
Lesson Chemistry: The Two Reactivity Series
A metal will only react with dilute acids if it is above hydrogen in the reactivity series. That is why hydrogen was included in the series given above. Activity 3 Use the reactivity series to predict how vigorous (fast) the following reactions will be: a. Zinc
Activity Series of Metals: Predicting Reactivity
28/2/2020· The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom. For example, both magnesium and zinc can react with hydrogen ions to displace H 2 from a solution by the reactions:

Add a 2–3 cm depth of dilute hydrochloric acid to the first three tubes, and a 2–3 cm depth of dilute sulfuric acid to the remaining three tubes. Add a small piece of a different metal to each of the tubes with hydrochloric acid in them. Record which metal you add
All metals above iron, itself included, react with dilute hydrochloric acid to produce a metal chloride and hydrogen. At the top of the reactivity series the metals react very violently with hydrochloric acid, and as the list goes down towards iron, the reaction with hydrochloric acid …

Although copper doesn''t readily react with dilute hydrochloric acid and dilute sulfuric acid (low in reactivity series), if heated with nasty oily concentrated sulfuric acid you make nasty pungent irritating sulphur dioxide gas and white anhydrous copper(II) sulfate, but this is NOT a reaction on which to base its place in the metal reactivity series and hydrogen gas isn''t produced.
