The reactivity of metals is because of their incomplete outer orbitals or due to their electronic configuration. The method used to extract metals from the ore in which they are found depends on their reactivity. AIM(i) To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions :(a) ZnSO4(aq. Aim To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions: ZnSO 4 (aq), FeSO 4 (aq), CuSO 4 (aq), Al 2 (SO 4) 3 (aq) To arrange Zn, Fe, Cu and Al metals in the decreasing order of reactivity based on the above results. CBSE Class 10 Science Lab Manual Salient features of the CBSE Class 10 Science Lab Manual are: Basic concepts of each experiment has been covered for better understanding. In a displacement reaction, a more reactive metal can displace a less reactive metal from its salt solution. Name the most reactive the least reactive metal. Properties of Acids and Bases
Common Salt - NaCl. Was the experiment/process motivating enough? Displacement Reaction: A single displacement reaction is also called a substitution reaction. Theory. Despite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals. )(d) Al2(SO4)3(aq. Viva Voce. When this layer is removed, the observations are more reliable. In these reactions, a free element displaces another element from its compound, producing a new compound. Add a small piece of Aluminum foil to each of these test tubes. What is a salt? 27/10. BASIC BUILDING CONCEPTS . Was the measurement and analysis of data easy for you? Observation: Reaction with cold water: Metals like sodium and potassium vigorously react with water to form its oxide and hydrogen gas. Double Displacement Reaction
