The production of the hydroxide (alkali) can be tested by adding universal indicator (UI) to the reaction vessel - UI changes from green to purple in the presence of these hydroxides. The reaction is relatively slow because of the existing strong aluminium oxide layer on the metal, and the build-up of even more oxide during the reaction. Solution: Amongst the given options, mercury and aluminium are metals while iodine and bromine are non-metals. Ans : [CBSE 2013] a. Mg, b. Cu 14. 4 Al (s) + 3 O 2 (g) 2 Al 2 O 3 (s) In general, the more reactive the metal, the more rapid the reaction. The process must be carried out in steam-heated vessels of nickel or steel , and the aluminium hydroxide should be boiled with approximately 50% aqueous caustic soda until a pulp forms. Reaction of aluminium metal with water: Reaction of aluminium metal with cold water is too slow to come into notice. Write the name of the product. aluminium does not react with water but ... on what you would consider a chemical reaction. (c) Calcium with water. It does react. Silicon. Iron reacts with steam according to the reaction 3Fe +4 H2O → Fe3O4 + 4H2O. +4H 2(g) . The reaction of metal (X) with ferric oxide is highly exothermic. Aluminum, especially with heated foods, spicy or acidic foods, leaches into the food while you’re cooking with foil wrap or with aluminum pots/pans. 2Al + 3H 2 O → Al 2 O 3 + 3H 2. Answers the following three questions note: you will need to write a balanced equation to answer them Al: 26.9 amu Fe: 55.8 amu O: 16 amu 1 How .
