Metals can react with water, acid and oxygen. Scroll down the page for examples and solutions. Aim: To examine the reactivity of metals with dilute hydrochloric acid. Test for presence of hydrogen gas with a match. Ideally all the metals would be in the same physical state, other than all being solids, i.e. Observations of the reaction of metals with cold water. same mass of the same sized granules or same sized sheet of same thickness - to give the same surface area in contact with the acid. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. In this experiment we will determine the relative reactivity of 4 metals: Copper, Iron, Zinc, and Magnesium Materials & ApparatusApparatusMaterials600 ml beakers tuberose splintered gatecrash glasstweezersscoopula lithium metabolism metastasis’s mathematical metered and blue litmus perpendicularity A- Reactions of Alkali Metals with Waterborne was half filled with water. Alkali Metals (Lithium, Sodium, Potassium) react with water. The reaction with water is as follows: Alkaline Earth metal + water Alkaline Earth metal hydroxide + hydrogen gas. Image credit fphoto.com. Alternatively use glass plates to cover the trough(s). Copper does not react with hydrochloric acid. The reactivity of the metal determines which reactions the metal participates in. Reactions of alkali metals with water All the alkali metals react vigorously with cold water. Reaction of metal and acid Single displacement reaction between magnesium and hydrochloric acid produce magnesium chloride and hydrogen gas. Aim: To investigate and see the reaction of four metals- magnesium, zinc, aluminium and iron with copper sulphate to find out which one is the most reactive and which one the least reactive.. Reactivity of Metals Experiment. Theory: The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. Experiment: The reaction of metals with dilute Hydrochloric acid. ZIMSEC O Level Combined Science Notes: Experiment: The reaction of metals with dilute Hydrochloric acid. All you need is a selection of metals, water, universal indicator, rack of test tubes and a splint. Add a drop of detergent (to stop the metals sticking to the side). Experiment 2: Reaction with water a Fill the trough(s) about half-full of water. Investigate the reactivity of metals. Place enough Universal indicator solution into each, with stirring, until the colour is clearly visible. The following table shows the reaction of metals in oxygen, water and acid. b At least two safety screens should be used, as close to the troughs as possible.
